Sliver Queen + Ashaya, Soul of the Wild + Blossoming Tortoise + Agatha of the Vile Cauldron

Sliver Queen

Ashaya, Soul of the Wild

Blossoming Tortoise

Agatha of the Vile Cauldron

How it works

1. Activate Sliver Queen by paying 0, creating a 1/1 Sliver creature token.
2. Repeat.

This loop is a masterclass in cost reduction turning an otherwise standard ability into an infinite engine. With Ashaya, Soul of the Wild on the battlefield, every nontoken creature you control—including Sliver Queen—becomes a Forest land in addition to its other types. This allows Blossoming Tortoise to step in and discount the ability costs of all those land creatures by {1}, while Agatha of the Vile Cauldron further reduces the activated abilities of your creatures by an amount equal to Agatha's power. By combining these overlapping cost reducers, the {2} activation cost of Sliver Queen is completely erased, letting you tap into free, endless token generation to flood the board with an infinite army.
