Sliver Queen + Ashaya, Soul of the Wild + Blossoming Tortoise + Glasspool Mimic // Glasspool Shore

Sliver Queen

Ashaya, Soul of the Wild

Blossoming Tortoise

Glasspool Mimic // Glasspool Shore

How it works

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

This clever loop relies on Ashaya, Soul of the Wild to turn every nontoken creature you control into a Forest land, which also grants them the land type thanks to its rules interaction. With Blossoming Tortoise on the field, the cost to activate your lands' abilities is reduced by {1}, making the Sliver Queen's token-creation ability entirely free instead of costing {2}. Meanwhile, Glasspool Mimic (playing its creature side, Glasspool Mimic // Glasspool Shore) can easily copy the Sliver Queen or another vital piece to help set the board state. By continuously paying {0} to activate Sliver Queen, you generate an endless army of tokens and enter-the-battlefield triggers completely free.
