Razzle-Dazzler

Prowess grows a body a defender can still trade with; this wizard's payoff outruns blockers entirely. Clear the second-spell threshold and it collects a permanent counter and slips past every creature for that combat, then does it again next turn, the evasion resetting each time. The counter is the memory and the unblockable clause is the delivery: the hit isn't a one-time surge but a standing invoice that comes due whenever you keep hitting that second cast. That's a sharper deal than prowess, whose pump is temporary and whose swing can be chumped or crashed into. The 1/2 body is the price of the mechanism. It survives the incidental pings that would sweep a 1/1, but it earns nothing on a turn where the second spell doesn't materialize; without the chain it's an idle creature doing no work at all. Only that second cast pays out: a third or fourth spell adds nothing, so the reward tracks consistency rather than raw volume. The whole thing is a wager that the deck around it can reliably fire twice a turn, and the counters only accumulate into a real clock inside a shell of cantrips, cheap instants, and interaction dense enough to make crossing that threshold routine. It punishes clunky curves and expensive spells and rewards the opposite: a low, spell-dense deck that clears two casts every turn turns this into an evasive threat that outgrows removal windows before the answer arrives.
