Tazri, Stalwart Survivor + Patrol Signaler + Agatha of the Vile Cauldron

Tazri, Stalwart Survivor

Patrol Signaler

Agatha of the Vile Cauldron

How it works

1. Activate Patrol Signaler by tapping it, adding that can only be spent to activate abilities.
2. Activate Patrol Signaler by paying and untapping it, creating a 1/1 Kithkin Soldier creature token.
3. Repeat.

This clever loop relies on Patrol Signaler doing double duty as both the token producer and its own untapper, thanks to the untap symbol in its activation cost. Ordinarily, Patrol Signaler's ability requires two white mana per iteration, but Agatha of the Vile Cauldron steps in to slash those generic costs down by her power, making the ability a breeze to fuel. To keep the engine running, Tazri, Stalwart Survivor grants every creature you control the ability to tap for a restricted mana of any of its colors, effortlessly converting Patrol Signaler's own tap into the exact white mana needed to pay the cost. By looping this process endlessly, you generate an infinite army of Kithkin Soldier tokens alongside a continuous stream of creature enters-the-battlefield triggers!
