Changes

Rio draws and activates the Field Spell Card "[[Ice Fire World]]" which will allow both players to treat a monster as two Overlay Units when Xyz Summoning a WATER Xyz Monster. Treating "Slyphine" as two materials now, Rio overlays it to Xyz Summon Rio overlays "it to Xyz Summon "[[Rioto Harpyia, the Cold Bird Princess]]" (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 prevent the destruction of "Black Ray Lancer" [[by battle]]" ("Black Ray Lancer" 4000/800 → 2100/800).
