Astroquarium (UNF 34, foil) is an uncommon artifact from Unfinity that can receive physical stickers as part of its enter-the-battlefield text. For {1} and tapping, it turns a target creature into a blue Shark 4/4 until end of turn, but if the art’s cracks are completely covered the creature becomes a blue Octopus 8/8 instead. The ability is sorcery-speed and the creature loses its previous colors and creature types while retaining other card types and supertypes.
