For those who have never heard of smash up, it is a living card game where players take 2 factions (say wizards and giant ants) and "smash" their decks together to battle each other for control of different bases. It's a really fun, fast paced game. Check it out. Smash up
Using this as inspiration and utilizing the new "Partner" mechanic in Commander 2016, I've decided to try and brew some 50 card decks that we can mash together to play some commander. (sure we could have done this before, but now it's completely legal)
