{{Duelprev|Featured Duel: Playmaker vs. Prototype Green-A}}

Playmaker has 4000 [[LP]] and controls no cards. Prototype Green-A has 3500 LP and controls "[[Tentacluster Nautilus]]" (0/↙↓↘) in the [[Extra Monster Zone]] and "[[Tentacluster Drillworm]]" (600/1200) in [[Defense Position]].

'''<u>Turn 2: Playmaker</u>'''<br />
Playmaker [[activate]]s the [[effect]] of "[[Dual Assembwurm (anime)|Dual Assembwurm]]" in his [[GY]], [[banish]]ing two other [[Cyberse]] monsters from his GY to [[Special Summon]] it, but its ATK becomes halved. He banishes "[[Dotscaper (anime)|Dotscaper]]" and "[[Linkslayer (anime)|Linkslayer]]", and Special Summons "Dual Assembwurm" (2800 → 1400/1000). As "Dotscaper" was banished, Playmaker activates its effect, Special Summoning it (0/2100). Playmaker activates the [[Equip Spell]] "[[Cynet Defrag]]", [[pay]]ing half his LP to activate it from the GY (Playmaker: 4000 → 2000 LP), [[target]]ing a [[Level]] 4 or lower Cyberse monster in his GY and Special Summoning it in [[Defense Position]], then [[equip]]ping "Cynet Defrag" to it. He targets, Special Summons, and equips "Cynet Defrag" to "[[Flick Clown (anime)|Flick Clown]]" (1000/1400). As Playmaker has no cards in his [[hand]], he activates the effect of "Flick Clown", paying 1000 LP to [[draw a card]] (Playmaker: 2000 → 1000 LP).

At this point, Playmaker enters the [[Data Storm]]. As Playmaker's LP is 1000 or less, he activates his [[Skill]] "Storm Access", accessing a Cyberse [[Link Monster]] at random from a nearby Data Storm and adding it to his [[Extra Deck]]. He obtains "Vector Scare Archfiend" and adds it to his Extra Deck.

Playmaker [[Link Material|sets]] "Dotscaper", "Dual Assembwurm", and "Flick Clown" in the [[Link Arrow]]s to [[Link Summon]] "[[Vector Scare Archfiend (anime)|Vector Scare Archfiend]]" (2400/↙↑→) to the Extra Monster Zone. Playmaker [[Normal Summon]]s "[[Cyberse Wizard (anime)|Cyberse Wizard]]" (1800/800). "Cyberse Wizard" [[attack]]s and [[destroy]]s "Drillworm", then "Vector Scare Archfiend" attacks and destroys "Nautilus" (Green-A: 3500 → 1100 LP). As "Vector Scare Archfiend" destroyed Green-A's monster by [[battle]], Playmaker activates its effect, [[Tribute|Tributing]] a monster to Special Summon the destroyed monster to Green-A's [[zone]] "Vector Scare Archfiend" [[points to]], then "Vector Scare Archfiend" can attack again in a row, on that monster. He Tributes "Cyberse Wizard", then Special Summons "Nautilus" to the zone the top-center Link Arrow of "Vector Scare Archfiend" points to. "Vector Scare Archfiend" attacks and destroys "Nautilus" (Green-A: 1100 → 0 LP).

The Duel is conducted as a [[Speed Duel]].

'''<u>Turn 1: Blue Angel</u>'''<br />
[[Skye Zaizen|Blue Angel]] [[activate]]s the [[Field Spell]] "[[Trickstar Light Stage (anime)|Trickstar Light Stage]]", [[Add a card|adding]] a "[[Trickstar]]" [[monster]] from her [[Main Deck|Deck]] to her [[hand]]. She adds "[[Trickstar Lilybell (anime)|Trickstar Lilybell]]". As "Lilybell" was added to Blue Angel's hand except by [[Draw a card|drawing]] it, she activates its [[effect]], [[Special Summon]]ing it (800/2000). Blue Angel [[Normal Summon]]s "[[Trickstar Candina (anime)|Trickstar Candina]]" (1800/400). As "Candina" was Normal Summoned, Blue Angel activates its effect, adding a "Trickstar" card from her Deck to her hand. She adds "Trickstar Vision". Blue Angel [[Link Material|sets]] "Lilybell" and "Candina" in the [[Link Arrow]]s to [[Link Summon]] "[[Trickstar Holly Angel (anime)|Trickstar Holly Angel]]" (2000/↙↘) to the [[Extra Monster Zone]]. Blue Angel activates the [[Spell]] "[[Trickstar Vision]]", Special Summoning a "Trickstar" monster from her hand, but its [[ATK]] becomes halved, also it has its effects [[negate]]d, then each player draws a card. She Special Summons "[[Trickstar Narkissus (anime)|Trickstar Narkissus]]" (1000 → 500/1800), then both players draw a card. Blue Angel [[Set]]s a card. Blue Angel activates the effect of "[[Trickstar Lycoris (anime)|Trickstar Lycoris]]" in her hand, [[reveal]]ing it, then [[target]]ing a different "Trickstar" monster she controls to Special Summon it, then [[return]] that monster to the hand. She targets "Narkissus", Special Summons "Lycoris" (1600/1200) to the [[zone]] the bottom-left Link Arrow of "Holly Angel" [[points to]], and returns "Narkissus" to her hand. Each time a "Trickstar" monster is Normal or Special Summoned to a zone "Holly Angel" points to, its effect inflicts 200 [[Effect damage|damage]] to [[Prototype Red-B|Red-B]] (Red-B: 4000 → 3800 [[LP]]). Each time a "Trickstar" monster Blue Angel controls inflicts [[Battle damage|battle]] or effect damage to Red-B, the effect of "Light Stage" inflicts 200 damage to him (Red-B: 3800 → 3600 LP). As Red-B took effect damage, Blue Angel activates the effect of "Narkissus" in her hand, Special Summoning it (1000/1800). She Special Summons it in [[Defense Position]].

As Red-B took damage by a "Trickstar" monster's effect, the effect of "Holly Angel" activates, increasing its ATK equal to the damage he took, until the end of this [[turn]] ("Holly Angel": 2000 → 2200 ATK). Red-B activates the [[Continuous Spell]] "[[Abyss Invitation]]". Red-B activates the effect of "[[Tentacluster Darkwhip]]" in its hand, [[pay]]ing 500 LP to Special Summon it (100/500) (Red-B: 3200 → 2700 LP). Each time Red-B activates a monster effect in his hand or [[GY]], the effect of "Narkissus" inflicts 200 damage to him immediately after it [[resolve]]s (Red-B: 2700 → 2500 → 2300 LP).

As Red-B took damage by a "Trickstar" monster's effect, the effect of "Holly Angel" activates, increasing its ATK equal to the damage he took, until the end of this turn ("Holly Angel": 2200 → 2400 ATK).

He targets "Darkwhip" and Special Summons two copies of "Darkwhip" (100/500). Red-B sets three copies of "Darkwhip" in the Link Arrows to Link Summon "[[Tentacluster Nautilus]]" (0/↙↓↘) to the Extra Monster Zone.

He Special Summons "[[Tentacluster Blastsucker]]" (400/400) to a zone "Nautilus" points to. Red-B Normal Summons "Blastsucker" (400/400) to a zone "Nautilus" points to. Red-B activates the effect of "Nautilus", targeting all monsters it points to and destroying them. He targets two copies of "Blastsucker". As a Link Monster's effect is activated that targets the two copies of "Blastsucker" on the field, Red-B activates their effects, destroying them, then inflicting 400 damage to Blue Angel (Blue Angel: 3600 → 3200 → 2800 LP).

As Red-B took damage by a "Trickstar" monster's effect, the effect of "Holly Angel" activates, increasing its ATK equal to the damage he took, until the end of this turn ("Holly Angel": 2400 → 2600 ATK). Red-B activates the effect of "Blastsucker" in his GY, banishing it to inflict 400 damage to Blue Angel (Blue Angel: 1400 → 1000 LP, Red-B: 1900 → 1700 → 1500 LP). As a player took 500 or less effect damage by the effect of another card, the effect of "Abyss Invitation" activates, inflicting 200 damage to Blue Angel (Blue Angel: 1000 → 800 → 600 → 400 LP). As Red-B took damage by a "Trickstar" monster's effect, the effect of "Holly Angel" activates, increasing its ATK equal to the damage he took, until the end of this turn ("Holly Angel": 2600 → 2800 ATK). Red-B activates the Continuous Spell "[[Flexible Tentacluster]]", and activates its effect, targeting one of his banished "Tentacluster" monsters and Special Summoning it in [[Attack Position]]. He targets and Special Summons "Blastsucker" (400/400). "Blastsucker" [[attack]]s "Lycoris". As Red-B's monster declared an attack, Blue Angel activates her [[face-down]] [[Trap]] "[[Trickstar Cascade]]", returning a "Trickstar" card she controls to the hand to negate the attack. She returns "Light Stage" and negates the attack of "Blastsucker".

'''<u>Turn 3: Blue Angel</u>'''<br />
Blue Angel Normal Summons "Candina" (1800/400). As "Candina" was Normal Summoned, Blue Angel activates its effect, adding a "Trickstar" card from her Deck to her hand. She adds "Trickstar Temptation". Blue Angel sets "Narkissus" and "Lycoris" in the Link Arrows to Link Summon "[[Trickstar Black Catbat (anime)|Trickstar Black Catbat]]" (2000/←→) to the zone the bottom-left Link Arrow of "Holly Angel" points to (Red-B: 1500 → 1300 LP). As a player took 500 or less effect damage by the effect of another card, the effect of "Abyss Invitation" activates, inflicting 200 damage to Blue Angel (Blue Angel: 400 → 200 LP). As Red-B took damage by a "Trickstar" monster's effect, the effect of "Holly Angel" activates, increasing its ATK equal to the damage he took, until the end of this turn ("Holly Angel": 2000 → 2200 ATK). As Red-B took damage by a "Trickstar" monster's effect, the effect of "Black Catbat" activates, reducing the ATK of all face-up monsters he controls by 200 for each monster "Black Catbat" points to, until the end of this turn. "Black Catbat" points to "Candina" ("Blastsucker": 400 → 200 ATK). As Blue Angel controls a "Trickstar" monster, she activates the [[Quick-Play Spell]] "[[Trickstar Temptation]]", targeting a monster on the field whose current ATK is different from its [[original ATK]] and returning it to the hand. He targets and returns "Blastsucker". "Holly Angel" attacks "Nautilus". Each turn, the first time Red-B would take battle damage from an attack involving his "Tentacluster" monster, the effect of "Flexible Tentacluster" prevents him from taking it.
