Henzie "Toolbox" Torre + Mortuary + Umbral Collar Zealot

Henzie "Toolbox" Torre

Mortuary

Umbral Collar Zealot

How it works

1. Cast the creature with MV>=4 for its blitz cost by paying 0.
2. Activate Umbral Collar Zealot by sacrificing the creature.
3. When the creature dies, it and Mortuary trigger.
4. Resolve the Mortuary trigger, putting it from your graveyard on top of your library.
5. Resolve the creature's trigger, causing you to draw it from the top of your library.
6. Resolve the Umbral Collar Zealot ability
7. Repeat.

This clever engine turns your command zone into an endless revolving door, fueled by Henzie "Toolbox" Torre's massive cost reduction that allows you to cast high-mana creatures for free. Once your creature hits the battlefield with blitz, Umbral Collar Zealot stands ready to sacrifice it on demand to trigger its death draw. That sacrifice also triggers Mortuary, instantly intercepting the creature on its way to the graveyard and placing it right back on top of your library where Henzie's draw trigger can pluck it straight back into your hand.
