Plague Myr card art
Plague Myr is a two-mana infect mana rock — it accelerates your gameplan while threatening poison counters every time it connects. In Urtet, Remnant of Memnarch builds, it also triggers Myr Galvanizer loops, making it one of the few cards in the format that pulls double duty as ramp and win condition.

Urtet, Remnant of Memnarch

73.4% of decks · synergy 0.71

Plague Myr is an auto-include in Urtet, Remnant of Memnarch — it counts as a Myr for untap triggers, feeds Myr Galvanizer combo lines, and deals infect damage if the board stalls.

03
Ixhel, Scion of Atraxa

Ixhel, Scion of Atraxa

55.9% of decks · synergy 0.53

Ixhel, Scion of Atraxa runs a proliferate-heavy gameplan where every poison counter already on an opponent compounds, so Plague Myr's infect ensures those counters land early and get multiplied.

05
The Scorpion God

The Scorpion God

35.4% of decks · synergy 0.35

The Scorpion God cares about -1/-1 counters, and Plague Myr's infect damage distributes them to players; it's a secondary angle that pressures opponents while the main engine kills creatures.

Commander is where Plague Myr does its best work — infect is slow against 40 life but mana rocks that also threaten an alternate win condition are exactly the kind of card poison strategies need. In Legacy and Vintage it's technically legal but competes against far more efficient acceleration and infect enablers, so it doesn't see meaningful play there. Modern has better two-mana ramp and dedicated infect payoffs, making Plague Myr a fringe consideration at best outside of Commander. Stick to EDH infect or Myr tribal shells — that's the format where the double role of ramp plus poison threat is actually worth a deck slot.
