Each creature spell you cast with mana value 4 or greater has blitz. The blitz cost is equal to its mana cost. (You may choose to cast that spell for its blitz cost. If you do, it gains haste and "When this creature dies, draw a card." Sacrifice it at the beginning of the next end step.)
Blitz costs you pay cost less for each time you've cast your commander from the command zone this game.
Henzie turns big creatures into hasty, disposable threats by giving them blitz, letting you flood the board with high-impact bodies, swing immediately, and draw a card when they die at end of turn. You ramp into fatties, chain blitz casts that get cheaper each time Henzie is recast, and grind out card advantage and value while ETB/dies triggers do the heavy lifting. You win by repeatedly slamming massive creatures, abusing enter/leave-the-battlefield effects, and going wide or wide-and-tall.
Add fast mana and ritual effects (Sol Ring, Jeska's Will, treasures) to power out fatties before the blitz discount comes online, plus sac outlets like Ashnod's Altar and Viscera Seer to bank value before the end-step sacrifice. Lean into Blood Artist–style aristocrats payoffs and recursion (Meren, Sheoldred, Eternal Witness) so dying creatures keep generating advantage. Top-end finishers (Craterhoof, Pathbreaker Ibex, Terastodon) and protection for Henzie tighten the deck into a high-power threat.
