Muldrotha, the Gravetide + Displacer Kitten + Sol Ring + Arcbound Ravager

Muldrotha, the Gravetide

Displacer Kitten

Sol Ring

Arcbound Ravager

How it works

1. Activate Sol Ring by tapping it, adding CC.
2. Activate Arcbound Ravager by sacrificing Sol Ring, putting a +1/+1 counter on Arcbound Ravager.
3. Cast Sol Ring from your graveyard by paying 1.
4. Displacer Kitten triggers, blinking Muldrotha.
5. Repeat.

This elegant loop uses Muldrotha, the Gravetide to turn your graveyard into an extension of your hand, letting you replay artifacts endlessly. You begin by tapping Sol Ring for mana, then feed it to Arcbound Ravager's sacrifice ability to grow the Ravager and clear the ring from the battlefield. Because Muldrotha allows you to play a permanent of each type from the graveyard on your turn, you simply cast Sol Ring anew. This noncreature spell immediately triggers Displacer Kitten, whose blink ability resets Muldrotha so you can repeat the process and pile infinite +1/+1 counters onto your board.
