Caldaia Strongarm

Blitz is what makes this card exist, because the body it is attached to would never justify five mana on its own. A 2/3 Warrior that plants two +1/+1 counters on a target creature when it arrives is a fine enough enters trigger, but stapled to a slow, forgettable frame it would sit unplayed. The blitz cost sells the trigger separately: pay , drop the counters immediately, and let the body evaporate at end of turn while the death rider replaces the card in your hand. That reframing turns a creature you were never meant to keep into something closer to a pump spell that draws a card, delivered at the same speed a hasted attacker can act. The counters land on a target of your choosing, so the payoff scales with whatever wants them: a creature with an outlast ability, a proliferate shell that will grow those two counters into more, or simply an attacker that needed the extra size to connect this turn. That is the tension blitz is built to resolve. A permanent whose long-term stats do not earn the mana becomes worth casting precisely because you agree to give it up, and the draw-a-card clause makes the sacrifice a wash rather than a loss. Cast at full price it is a modest counter enabler you can hold; cast for blitz it is a burst of board development that costs you nothing in cards. Same trigger, two entirely different jobs depending on how you pay.
