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
There’s a bit in a game called “Cow Life Sim RPG” about this and it’s one of my favorite bits ever, but to really h see stand it you hafta go play the game. It’s the best shitpost game ever made and I love it so much.
