Vigean Graftmage + Animate Land + Utopia Sprawl + Izzet Boilerworks

Vigean Graftmage

Animate Land

Utopia Sprawl

Izzet Boilerworks

How it works

1. Cast Animate Land by paying , causing Izzet Boilerworks to become a creature until end of turn.
2. Put a +1/+1 counter on Izzet Boilerworks.
3. Activate Izzet Boilerworks by tapping it, adding .
4. Utopia Srawl triggers, adding one mana of the chosen color.
5. Activate Vigean Graftmage by paying 1, untapping Izzet Boilerworks.
6. Repeat.

This delightful loop turns a humble bounceland into a self-sustaining mana engine by turning it into a creature with Animate Land and outfitting its Forest type with Utopia Sprawl for extra mana generation. Because Izzet Boilerworks enters the battlefield tapped, granting it creature status allows Vigean Graftmage to target and untap it using the mana it produces, while the graftmage's untap ability is fueled over and over. Every time you tap the animated land for its blue and red mana, Utopia Sprawl chips in an extra colored mana of your choice to ensure you net positive mana on each iteration of the loop.
