Displacer Kitten + Great Whale + Ghitu Firebreathing

Displacer Kitten

Great Whale

Ghitu Firebreathing

How it works

1. Activate up to seven lands you control by tapping them, adding at least 1.
2. Cast Ghitu Firebreathing by paying its mana cost, targeting Displacer Kitten
3. Displacer Kitten triggers, blinking Great Whale.
4. When Great Whale enters the battlefield, it triggers, untapping up to seven lands.
5. Resolve the Ghitu Firebreathing spell.
6. Activate Ghitu Firebreathing by paying , returning it from the battlefield to your hand.
7. Repeat.

This ingenious loop relies on Displacer Kitten's avoidance ability to continuously recycle Great Whale whenever you cast a noncreature spell. By enchanting a creature with Ghitu Firebreathing, you gain a cheap, instant-speed spell that you can cast repeatedly, thanks to the Aura's own ability allowing you to return it to your hand for a single red mana. Each iteration triggers the Great Whale to enter the battlefield and untap your lands, generating a massive surplus of mana to fuel the entire engine while storming off.
