mtg purple cards Pentapus | Avatar: The Last Airbender Eternal Emptiness

Golgari has a lot of self-mill effects that will trigger this card drawing ability from your deck, and between Crucible of Worlds, Ramunap Excavator, or Regrowth effects, you can easily treat your graveyard as an extension of your hand when needed

So many big permanents now are about ETBs and things though that dumping mana into this unless it's just to turn it into a huge beater kind of loses something

Storage Tray for Accessories: Dice, counters, and tokens have a dedicated space

Tomb of Annihilation doesnt need to go in your deck, and venture into the dungeon effects are plentiful, meaning you can conjure The Atropal almost as an afterthought
