This deck is pretty much just a second draft on my prior build. I got some amazing suggestions from the GLC community on discord and started honing the focus of this deck. Though I still need to playtest it, in theory, you should be able to open with some spread damage and close with Dusknoir's Sinister Hand Ability plus some big swing damage from Necrozma, Dragapult, and Gardy.
Who's on the bubble? Giratina. It's a great backup attacker for this deck but the 40 damage backlash is not ideal. Maybe cut for suspicious food tin.
I'm also trying to figure out how to include the Celebrations Lunala line. Her Lunar Pain attack could make for some unique combos here. It's a stage 2 line so I'd have to make some tricky cuts to make room. Thoughts?
