Abdel Adrian, Gorion's Ward + Planar Incision + Greenwarden of Murasa

Abdel Adrian, Gorion's Ward

Planar Incision

Greenwarden of Murasa

How it works

1. Cast Planar Incision by paying its mana cost, blinking Abdel Adrian.
2. Abdel Adrian leaves the battlefield, returning Greenwarden of Murasa and all other cards that were exiled with it to the battlefield.
3. Abdel Adrian and Greenwarden of Murasa trigger.
4. Resolve the Greenwarden of Murasa trigger, returning Planar Incision 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 Planar Incision.
6. Resolve the Abdel Adrian trigger, exiling Greenwarden of Murasa 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 brilliant loop turns Abdel Adrian, Gorion's Ward into a permanent-blinking engine fueled by Planar Incision and Greenwarden of Murasa. When Abdel Adrian enters the battlefield, he exiles Greenwarden of Murasa along with your mana-producing permanents, which conveniently allows you to tap them for mana before they vanish and sets up a cascade of entering-the-battlefield triggers. Casting Planar Incision restarts the cycle by blinking Abdel Adrian, letting Greenwarden of Murasa pull the spell right back out of your graveyard while the freshly freed permanents ready themselves to be tapped all over again.
