Vivi Ornitier + Agatha's Soul Cauldron + Geralf, the Fleshwright + Mind Games

Vivi Ornitier

Agatha's Soul Cauldron

Geralf, the Fleshwright

Mind Games

How it works

1. Cast Mind Games with buyback by paying 2
2. Geralf triggers, creating a 2/2 Zombie Rogue creature token.
3. When the Zombie Rogue enters the battlefield, Geralf's second ability triggers, putting a +1/+1 counter on the Zombie Rogue for each other Zombie that entered the battlefield under your control this turn.
4. Resolve the Mind Games spell, returning it to your hand.
5. Activate the Zombie Rogue using Vivi's ability by paying 0, adding an amount of equal to its power.
6. Repeat.

This loop turns a simple tap spell into an infinite storm and mana engine by cycling Mind Games with its buyback cost, triggering Geralf, the Fleshwright to flood the board with Zombie Rogue tokens. Agatha's Soul Cauldron is the hidden linchpin here, allowing your creatures to inherit Vivi Ornitier's activated ability once they bear +1/+1 counters from the Cauldron or Geralf's own growth triggers. Each new token thus gains the power to tap and tap into Vivi Ornitier's mana-generation scaling directly off its own pumped-up power, fueling the loop infinitely.
