Notes & Combos

Hit Dlv. Max for the first time using one of my new favorite decks. List is kinda scuffed but works well. Absorb Fusion is a solid (and cheap) searcher for pure. The second Phantom Quartz was VERY useful in grind games, and S:P was really good the couple times it came up. Garnet is funny but also pretty nice to have as a secondary send for Hollowcore or hard summoning Ruby. Had a blast using the deck. Master Diamond is my GOAT.
