This charming swarm loop turns a modest ant farm into a hyper-efficient mana engine, powered entirely by a clever doubling effect and some clever botanical engineering. You begin by activating Kaya, Geist Hunter's minus-two loyalty ability, setting up a replacement effect that ensures any token creation for the rest of the turn yields twice the usual yield. With that threshold crossed, Ant Queen can feed its own appetite: by paying just one green and one generic mana, the queen produces a pair of buzzing bugs instead of one, thanks to Kaya's lingering static buff. Meanwhile, Jaheira, Friend of the Forest quietly transforms those newly minted Insect tokens into full-fledged mana dorks, granting each one the ability to tap for green mana. Since it costs two mana to activate Ant Queen and you get two green mana back from tapping the resulting token pair, you can repeat the process infinitely to flood the board with an endless sea of tapped bugs. While Frostcliff Siege and its Temur choice don't actively participate in generating the loop itself, they sit quietly on the battlefield ready to hand out haste, trample, and stat buffs to your massive, freshly doubled army once the loop concludes.
