Bant Cube Induced Madness
My partner and I drafted the bant (White, Blue, and Green) cube I built for her and it was fun, but it was definitely a game where you understand why there are 5 colors in magic and not 3.
I had a Cathar's Crusade Tokens deck, and she had a 3 color counters deck with Spike Weaver. We were at a standstill for so long that we eventually just called it a draw cause she has to leave for work soon. It was a fun bit of torture xD
