Displacer Kitten + Great Whale + Agoraphobia

Displacer Kitten

Great Whale

Agoraphobia

How it works

1. Activate up to seven lands you control by tapping them, adding at least 3.
2. Cast Agoraphobia 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 Agoraphobia spell.
6. Activate Agoraphobia by paying 2, returning it from the battlefield to your hand.
7. Repeat.

This clever loop turns the self-bouncing nature of Agoraphobia into a devastating engine by leveraging Displacer Kitten's avoidance ability to continuously blink Great Whale. Every time you recast Agoraphobia as a noncreature spell, the Kitten triggers to exile and return the Whale, whose entry ability untaps your lands to fuel both the spell's initial cost and its return activation of {2}{U}. Because Agoraphobia can simply be bounced back to your hand rather than leaving you short on resources, you generate infinite mana from your lands alongside boundless enters-the-battlefield and leaves-the-battlefield triggers.
