This cube aims to have a minimal level of "unfun" cards in it, and I try to eliminate most infinite combos (as far as I'm aware...) and other complex interactions that involve a strong background in the game. It's all about having a blast while in good company, while keeping the learning curve a bit more beginner friendly. There are lots of fun themes like Zombie and human tribal, GW tokens/+1/+1 counters, blue weenies, sultai self-mill, the rare-but-doable reanimator, sneak & show type builds, etc.
Enjoy the cube, and please leave any feedback or constructive criticism you may have--I'm all ears! Just keep in mind the objectives I listed above :^)
