This started as a Winston Draft deck. Firion, Wild Rose Warrior would have probably slipped through my notice as a powerful Party Leader if I hadn’t pulled him during the draft. I don’t often play mono color decks, but he ended up being extremely fun with big swings and fun decisions once the copies disappear.
The goal of the deck is to play cheap creatures until turn 3 so you can get Firion on the table. By that point you should have at least one equipment in your hand. Just about every equipment in the Final Fantasy set spawns a hero that gets equipped to it, so Firion doubles that effect as well. You can use them to attack, or use the 
discount to move the equipment to more powerful creatures.
