Changes

Rio draws and activates the Field Spell Card "[[Ice Fire World]]" which will allow both players to treat a WATER monster as two Overlay Units when Xyz Summoning. Treating "Slyphine" as two materials now, Rio overlays it to Xyz Summon "[[Rioto HarpyiaHarpyuia, the Sub-Zero PrincessSovereign]]" (2500/2100) in Attack Position. Rio activates the effect of "Rioto Harpyia," detaching an Xyz Material to reduce the ATK of "Black Ray Lancer" to 0 (4000 → 0). "Rioto Harpyia" attacks "Black Ray Lancer" (Shark 3000 → 500), but Shark activates the effect of "Full-Armored Xyz", [[send]]ing the equipped "Aero Shark" to the Graveyard to prevent the destruction of "Black Ray Lancer" [[by battle]]" ("Black Ray Lancer" 4000/800 → 2100/800).

Shark Normal Summons "[[Drill Barnacle]]" (300/0). He then activates "[[Xyz Jeweled Crown]]", equipping it to "Black Ray Lancer", letting him treat it as a Level 3 monster and allowing it to be treated as two Overlay Units for an Xyz Summon. Shark overlays "Black Ray Lancer" with "Drill Barnacle". The latter card is also treated as two Overlay Units via the effect of "Fire Ice World". Shark Xyz Summons "[[Fanged Shark Emperor - Shark CaesarKaizer]]" (1800/2000) in Attack Position. Shark activates the effect of "Shark Kaiser", detaching an Overlay Unit to increase its ATK by the original number of Overlay Units required to Xyz Summon it minus the current number of Overlay Units [[attach]]ed to it x 1000. (1800 → 4800). "Shark Kaiser" attacks and destroys "Rioto Harpyia" (Rio 2300 → 0).
