How it works
Cast High Perfect Morcant either from your hand or the command zone by paying 2 plus commander tax if applicable.
When High Perfect Morcant enters, its first ability triggers, causing each opponent to put a -1/-1 counter on a creature they control.
Flourishing Defenses triggers for each counter placed this way. Resolve the first trigger, creating a 1/1 Elf Warrior creature token.
