{{episode summary|The [[Arc League Championship]] finally kicks off. Following [[Frederick]]'s smooth victory as the first representative for [[You Show Duel School]], [[AllyAllie]] is next to Duel for the Youth. AllyAllie's opponent is [[Riley Akaba|Riley]], known as "The Treasure of [[Leo Institute of Dueling]]". In contrast of the enthusiastic Ally Allie who receives the support of everyone, Riley seems to be afraid of something. While [[Declan Akaba|Declan]] and [[Henrietta Akaba|Henrietta]] watch, Riley utilizes a strange strategy to copy Ally's monsters.}}

==Featured Duel: Ally Allie vs. Riley Akaba==[[File:Ayu VS Layra.png|thumb|left|[[AllyAllie]] vs [[Riley Akaba|Riley]]]]

<u>'''Turn 1: AllyAllie'''</u><br />[[AllyAllie]] [[Normal Summon]]s "{{TooltipA|Aquaactress Guppy (anime)}}". She activates the [[Continuous Spell Card]] "{{TooltipA|Aquarium Stage (anime)}}", preventing her [[WATER]] [[Monster Card|monsters]] from being [[destroyed by battle]] except by other WATER monsters. She then activates the [[Continuous Spell Card]] "{{TooltipA|Aquarium Set (anime)}}", increasing the [[ATK]] of all "[[Aquaactress]]" monsters on the [[field]] by 600 ("Guppy" 600 → 1200). Ally Allie finally activates the Continuous Spell Card "{{TooltipA|Aquarium Lighting (anime)}}", doubling the ATK of all "Aquaactress" monsters until the end of the [[Battle Phase]] when they [[battle]] another monster. Ally Allie calls for the [[attack]] of "Guppy", but is unable to since the Battle Phase can't be conducted during the first turn. Ally Allie [[Set]]s a card.

[[Riley Akaba|Riley]] activates "{{TooltipA|Shutter Layer 1}}", [[Target|targeting]] a monster Ally Allie controls and [[Special Summon]]ing the former as a [[Normal Monster]] with the same name, [[Type]], [[Attribute]], [[Level]], [[ATK]], and [[DEF]]. He targets "Guppy", Summoning "Layer 1" as a copy of that card (600/600). By the effect of "Aquarium Set", it gains 600 ATK (Riley's "Guppy" 600 → 1200). Riley [[Set]]s a card.

<u>'''Turn 3: AllyAllie'''</u><br />Ally Allie Normal Summons "{{TooltipA|Aquaactress Tetra (anime)}}" ("Tetra" 300 → 900). She finds the Action Card "{{TooltipA|Sunshine Smile}}". AllyAllie's "Guppy" attacks Riley's, and she activates "Sunshine Smile", increasing the ATK of her "Guppy" by 400 until the end of the Battle Phase (AllyAllie's "Guppy" 1200 → 1600). During the [[Damage Step]], "Aquarium Lighting" doubles the ATK of both "Guppy" (AllyAllie's "Guppy" 1600 → 3200, Riley's "Guppy" 1200 → 2400). Riley's "Guppy" and "Layer 1" are destroyed (Riley: 4000 → 3200 LP). "Tetra" attacks [[direct attack|directly]] (Riley: 3200 → 2300 LP).

Riley activates the Continuous Spell Card "{{TooltipA|Shutter Layer 2}}", preventing AllyAllie's cards from being affected by her own card effects (AllyAllie's "Guppy" 1200 → 600, AllyAllie's "Tetra" 900 → 300). Riley activates another "Shutter Layer 1", once again targeting "Guppy" and Summoning itself as a copy of the targeted monster (600/600). By the effect of "Aquarium Set", it gains 600 ATK (Riley's "Guppy" 600 → 1200). Riley's "Guppy" attacks and destroys AllyAllie's "Tetra", with "Aquarium Lighting" doubling the former's ATK during the Damage Step (Riley's "Guppy" 1200 → 2400; AllyAllie: 4000 → 1900 LP).

<u>'''Turn 5: AllyAllie'''</u><br />Ally Allie [[Tributes]] "Guppy" to [[Tribute Summon]] "{{TooltipA|Aquaactress Arowana (anime)}}". Because the monster it was targeting left the field, "Layer 1" is destroyed. "Arowana" attacks directly, but Riley activates his [[face-down]] "{{TooltipA|Instant Shutter}}", Special Summoning it as a [[Normal Monster]] with the same name, Type, Attribute, Level, ATK, and DEF as "Arowana" (2000/2000), but it will be destroyed at the end of the Battle Phase. By the effect of "Aquarium Set", it gains 600 ATK (Riley's "Arowana" 2000 → 2600). Ally Allie activates her face-down "{{TooltipA|Aqua Story - Urashima (anime)}}", [[banish]]ing two "Aquaactress" monsters from her Graveyard to make the ATK of one of her opponent's monsters 100 and prevent its ATK from being changed by other card effects this turn. She banishes "Guppy" and "Tetra" and targets Riley's "Arowana" (2600 → 100). "Arowana" attacks and destroys "Arowana" (Riley: 2300 → 400 LP).

Riley Normal Summons "{{TooltipA|C/C Critical Eye}}". He then activates the Continuous Spell Card "{{TooltipA|Montage Fusion}}", allowing him to [[Fusion Summon]] a [[Fusion Monster]] in his [[Extra Deck]] as long as both him and his opponent control the required [[Fusion Material Monster]]s. Since Ally Allie controls a WATER monster, he uses his "C/C Critical Eye" to Fusion Summon "{{TooltipA|C/C/C Water Sword of Battle}}". "Water Sword" attacks and destroys "Arowana", with its effect increasing its ATK by the ATK of all other WATER monsters on the field ("Water Sword" 2400 → 4400; AllyAllie: 1900 → 0 LP).
