Correct, I jumped the gun thinking I had a 7gdl option in trash as well but that was g1💀 and then I only had duplicate names (inc Leviamon and Rage Mode) in trash. Just started playing again and borrowed the deck so ironing out the creases lol
you can tell the demon lord player didn't know the matchup well. doing things like calling to grab 2 ruin mode and stocking up your hand for mirage to play into is asking to lose.
