Surge Engine

Two mana of accrued investment before the card ever throws a punch, then ten more spent across three chained upgrades: pay to shed defender and become unblockable, to swell into a 5/4 body, once to cash the whole thing out for three cards. It is a leveler in the spirit of the term Rise of the Eldrazi coined, a single permanent that starts as a wall, ends as a beater, and finally converts its own stat line into card advantage. The sequencing constraints are the spine of the design: the growth clause checks that defender is already gone, and the draw checks that the creature is blue, which only the middle activation makes it, so the abilities have to fire in order. That ordering turns a fragile 3/2 into a deliberate mana sink for a control shell with nothing better to do with its late-game floods, a one-card curve that answers "what do I do with twelve open mana" without dedicating a slot to a dedicated payoff. Blue rarely gets its beatdown and its card draw stapled to the same body, and the toughness of 2 keeps the early stages honest: this is a creature you protect and invest in, not one you ambush with. The whole apparatus rewards patience the way a mono-blue tempo engine rarely asks for it, front-loading commitment in exchange for a game-ending draw step you build toward one activation at a time.
