Baron Helmut Zemo
Legendary Creature — Human Noble Villain
What the Card Says
Whenever you cast a black spell from your hand, Baron Helmut Zemo connives. Boast — Exile any number of black cards from your graveyard with fifteen or more black mana symbols among their mana costs: Copy those exiled cards. You may cast up to three of the copies without paying their mana costs. (Activate only if this creature attacked this turn and only once each turn.)
What Does That Mean
This is a 3/3 creature that triggers "connive" whenever you cast a black spell from your hand (connive means you draw a card, then discard a card, and if you discarded a nonland card, put a +1/+1 counter on this creature).
Its boast ability lets you exile black cards from your graveyard that have 15+ total black mana symbols across all of them, then copy those cards and cast up to three copies for free—but only once per turn if the creature attacked.
Why Is That Important
Baron Helmut Zemo fits into black-heavy control or midrange decks that naturally cast many black spells and fill the graveyard with high-mana-value cards.
The connive trigger provides card advantage and incremental growth each turn, while the boast ability can generate massive value by cheating expensive spells like planeswalkers or X-spell payoffs directly into play.
It works particularly well in self-mill or graveyard-focused strategies where you're already discarding or milling powerful black cards, turning your graveyard into a resource rather than waste.
