Agatha of the Vile Cauldron + Silvanus's Invoker + Shimmerwilds Growth

Agatha of the Vile Cauldron

Silvanus's Invoker

Shimmerwilds Growth

How it works

1. Activate the land with Shimmerwilds Growth attached by tapping it, adding 1.
2. Shimmerwilds Growth triggers, adding 1.
3. Activate Silvanus's Invoker by paying 1, untapping Gruul Turf and causing it to become an 8/8 Elemental with trample and haste in addition to its other types until end of turn.
4. Repeat.

By leveraging Agatha of the Vile Cauldron's passive cost-reduction, we can dramatically slash the activation price of Silvanus's Invoker down to just a single mana. To fuel this indefinitely, Shimmerwilds Growth enchants a land to double its mana production, allowing that single tapped land to generate the exact {1} needed to untap itself. This creates an infinite loop that yields limitless mana, alongside boundless untaps and massive stats for your lands.
