Mariposa Military Base enters tapped and produces colorless mana, but its real job is spreading radiation counters — which translates directly into poison counters on opponents through The Wise Mothman's trigger. The setup cost is real: a tapped land that only makes colorless is a meaningful tempo loss, so you run it because the poison payoff is worth the awkward mana.

Commanders with the highest synergy
The Wise Mothman
The Wise Mothman turns every radiation counter into a poison counter for each opponent, and Mariposa Military Base is one of the cleanest repeatable sources of radiation in the format — the land does the spreading just by being in play and tapping.
The Master, Transcendent
The Master, Transcendent wants bodies to convert and proliferate effects to stack up counters; Mariposa Military Base feeds that engine by generating radiation counters that proliferate can then copy across the board.

Commander is where Mariposa Military Base belongs — the radiation-into-poison line only goes wide enough to matter in a multiplayer game where you're tagging three opponents at once. In Legacy and Vintage, the card is technically legal but has no competitive home: colorless tapped lands are a liability in formats where speed defines everything, and the poison synergy has no meaningful support. Oathbreaker could theoretically host a Mothman-style build at a smaller table, but the poison count threshold gets much harder to reach with only one opponent.

Price Context
Current price
$0.29 bulk tier
At $0.29, Mariposa Military Base is firmly bulk — easy to pick up as a four-of if you need it. It's a staple in a narrow archetype rather than a broadly demanded card, so don't expect the price to move unless radiation strategies get a significant new piece.
