Abdel Adrian, Gorion's Ward + Mnemonic Wall + Splash Portal

Abdel Adrian, Gorion's Ward

Mnemonic Wall

Splash Portal

How it works

1. Cast Splash Portal by paying its mana cost, blinking Abdel Adrian.
2. Abdel Adrian leaves the battlefield, returning Mnemonic Wall and all other cards that were exiled with it to the battlefield.
3. Abdel Adrian and Mnemonic Wall trigger.
4. Resolve the Mnemonic Wall trigger, returning Splash Portal from your graveyard to your hand.
5. Holding priority, activate any number of nonland permanents you control by tapping them, adding at least enough mana to cast Splash Portal.
6. Resolve the Abdel Adrian trigger, exiling Mnemonic Wall and the mana-producing permanents until Abdel Adrian leaves the battlefield, and creating a 1/1 Soldier creature token for each permanent exiled this way.
7. Repeat.

This elegant loop puts Abdel Adrian, Gorion's Ward at the center of a self-sustaining blink engine, repeatedly chewing up and spitting out your board. By casting Splash Portal, you exile and return Abdel Adrian to continuously trigger his exile ability, which swallows up Mnemonic Wall alongside any mana-producing permanents you control. Every time Mnemonic Wall crashes back onto the battlefield, it fishes Splash Portal right back out of your graveyard to hand, setting you up to cast it again. The result is an explosive cascade of infinite creature tokens, enter-the-battlefield triggers, and storm count that easily overwhelms your opponents.
