Pack the deck with Warriors you want to clone with the likes of Jaxis, the Troublemaker, Feldon of the Third Path, and Kiki-Jiki, Mirror Breaker

Play 2: Jean-Emmanuel Deprazs Soaring Thought-Thief Jean-Emmanuel Depraz (UB Rogues) vs Yoshihiko Ikawa (Jeskai Mutate), Top 8 of the MPL Gauntlet (2021) Youre in a pretty bad spot: your opponent has a lethal threat and, even though you have a blocker this turn, you have nothing else for future turns

If you have fewer than four creature cards in your graveyard at that time, the ability won't trigger at all
