By using Master Chef to grant your commander and other creatures the ability to enter the battlefield with an extra +1/+1 counter, you completely negate the mechanical drawback of persist creatures that usually limits them to a single revival. As you repeatedly activate Phantom Train by sacrificing that persist creature, the creature dies only to immediately return with a fresh +1/+1 counter from Master Chef, which instantly cancels out any lingering -1/-1 counters and sets up an infinite loop. This engine generates infinite sacrifice triggers, creature leave-the-battlefield and enter-the-battlefield events, and as many +1/+1 counters as you could possibly desire on Phantom Train.
