Prerequisites

• The Ooze on the battlefield
• Atog on the battlefield
• Master Chef on the battlefield
• March of the Machines on the battlefield

Steps

1. Activate Atog by sacrificing a creature with a +1/+1 counter on it
2. When that creature dies, The Ooze triggers, creating a Mutagen artifact token for each +1/+1 counter on the sacrificed creature
3. These artifacts are also 0/0 creatures due to March of the Machines
4. Each Mutagen artifact creature token enters with at least one +1/+1 counter on it due to Master Chef
5. Resolve the Atog ability, giving it +2/+2 until end of turn
6. Repeat from step 1
