Displace + Mnemonic Wall + Great Whale

Displace

Mnemonic Wall

Great Whale

How it works

1. Activate up to seven lands by tapping them, adding at least 2.
2. Cast Displace by paying 2, blinking Mnemonic Wall and Great Whale
3. When Mnemonic Wall and Great Whale enter the battlefield, their abilities trigger.
4. Resolve the Mnemonic Wall trigger, returning Displace from your graveyard to your hand.
5. Resolve the Great Whale trigger, untapping up to seven lands.
6. Repeat.

This elegant loop is powered by the synergy between Mnemonic Wall and Great Whale, two creatures whose powerful enters-the-battlefield triggers completely refund the cost of their own rescue. By casting Displace, you exile both creatures and return them to the battlefield simultaneously, allowing Mnemonic Wall to pluck Displace right back out of your graveyard while Great Whale untaps your lands to pay for the spell all over again. Because Displace targets two creatures, it serves as the perfect engine to repeat this cycle endlessly, generating infinite mana and effects.
