Abdel Adrian, Gorion's Ward + Izzet Chronarch + Cloudshift

Abdel Adrian, Gorion's Ward

Izzet Chronarch

Cloudshift

How it works

1. Cast Cloudshift by paying its mana cost, blinking Abdel Adrian.
2. Abdel Adrian leaves the battlefield, returning Izzet Chronarch and all other cards that were exiled with it to the battlefield.
3. Abdel Adrian and Izzet Chronarch trigger.
4. Resolve the Izzet Chronarch trigger, returning Cloudshift 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 Cloudshift.
6. Resolve the Abdel Adrian trigger, exiling Izzet Chronarch 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 clever loop gets rolling when you use Cloudshift to blink Abdel Adrian, whose entry triggers exile Izzet Chronarch right alongside your mana-producing permanents while flooding the board with 1-1 Soldier tokens. As Izzet Chronarch re-enters the battlefield, its triggered ability immediately fishes Cloudshift right back out of your graveyard and into your hand. This sets you up to replay Cloudshift, repeating the cycle to generate infinite entry and leave-the-battlefield triggers, an arbitrarily large storm count, and an endless army of tokens.
