Hahaha that sounds fun too!
My favorites that I made were an actually good legacy elf deck that could win on turn 2-3 with Staff of Domination or Emrikul (my favorites, some other good wincons too) and my very casual but mean Memory Jar/Megrim deck that I used when I was playing people who didn’t have proper legacy decks. The megrim deck was like 15 years ago, before I got into competitive Magic hahaha
Could I ask what movie? I’m curious!
