Hydro-Man, Fluid Felon

Legendary Creature — Elemental Villain

Hydro-Man wants a deck that makes huge amounts of mana for giant spells. It also works in a deck built around Elementals or Villains.

Whenever you cast a blue spell, if Hydro-Man is a creature, he gets +1/+1 until end of turn.

At the beginning of your end step, untap Hydro-Man. Until your next turn, he becomes a land and gains "tap: Add blue." (He's not a creature during that time.)
