Managed to snag Yugi form (resummon every turn), Deva form ( 1 to energy every turn) thanks to Prismatic Shard (gives cards from other classes), Imperial Orders (makes a random card 0 cost), Miraculous Descent (a power that gave me high defense cards every turn) and a lot of orbs that either damaged every turn (lightning) or with every card played (fire). A deck full of temporary HP (with the added bonus of costing zero and increasing my summons for stronger cards or even energy cards) made sure my defenses were always high even in the preparation phases. When the powers were on, even when fully powered, the heart barely put a dent in me (ended the fight with 100 shield, temporary hearts in the 50s and counting), and I barely explored the golden cards. If you want to feel like a beast, please do try it.
