Repository Skaab + Walk the Aeons + Muldrotha, the Gravetide

Repository Skaab

Walk the Aeons

Muldrotha, the Gravetide

How it works

1. Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Repository Skaab either from your hand or from your graveyard by paying 3.
3. When Repository Skaab enters, its exploit ability triggers, causing you to sacrifice it.
4. Repository Skaab's second ability triggers, returning Walk the Aeons from your graveyard to your hand.
5. Repeat each turn.

This elegant loop grants you infinite turns by recycling a single extra-turn spell right out of your graveyard. Muldrotha, the Gravetide provides the crucial foundation here, letting you cast Repository Skaab directly from your graveyard turn after turn. When Repository Skaab enters the battlefield, its exploit ability lets you sacrifice it to its own trigger, which then fires off its second ability to return Walk the Aeons from your graveyard straight to your hand. Because Muldrotha also allows you to play your land drop each turn—or recast other permanents if needed—you can continuously relaunch Walk the Aeons to keep taking extra turns indefinitely.
