Myr Propagator card art
Myr Propagator turns any untap loop or token doubler into an exponentially growing army of Myr — the ceiling is genuinely broken. The cost is a three-mana 1/1 that does nothing without support, and Intruder Alarm or Urtet, Remnant of Memnarch are mandatory to make that payoff real.

Urtet, Remnant of Memnarch

55.3% of decks · synergy 0.54

Urtet, Remnant of Memnarch untaps all your Myr during combat, which turns Myr Propagator into a geometric token engine every single attack step — no extra pieces required beyond what the deck already wants.

Mairsil, the Pretender can exile Myr Propagator with a cage counter and activate its copy ability as many times per turn as the rules allow, producing Myr tokens without ever needing the original on the battlefield.

Commander is the only format where Myr Propagator is worth a slot — the 100-card singleton environment gives it access to Intruder Alarm, dedicated Myr tribal commanders, and enough redundant untap effects to fire the engine consistently. In Legacy and Vintage it's legal but unplayable; three mana for a 1/1 that requires setup doesn't compete in those contexts. Modern sees it the same way — the card exists on the legality list and nowhere else. Myr Propagator is a Commander card through and through.

Price Context

Current price

$1.10 cheap tier

At $1.10, Myr Propagator sits at the low end of niche tribal combo pieces — cheap enough that the ask is trivial for any Myr deck. Demand is narrow but stable; this isn't a card that spikes, but it also doesn't crater because the player base that wants it knows exactly why.
