The B Team desperately wants to be a powered Vintage cube. The only rule for the cube is that it can't use any cards that are already in my high powered vintage cube, so it fails spectacularly, but can still be pretty strong and has some pretty dumb ways to win. It's like if you bought your vintage cube on Temu.
One mana two powered beaters, infinite combos, control spells, salt-inducing creatures, they're all here. Just not the ones you really want. Polluted Delta? Nope, but I have a Bad River for you. Triomes? Sure, just the Jungle Shrine and Sandsteppe Citadel kind. Lightning Bolt? Nope, but Unholy Heat is even better! Ask for a Griselbrand, get a Gurmag Angler. Ordered a Counterspell? Sorry, there's been a Delay. Black Lotus? Here, have a Coldsteel Heart! Balance? How about Magus of the Balance...
And of course, because I'm terrible at rules, the one rule is already broken with the LoTR common land cyclers. There are no good lands for them to fetch anyways!
