Legacy UGR Threshold deck
UGR threshold is a deck that abuses the threshold mechanic from Odyssey. It uses cards such as Brainstorm to reach threshold as quickly as possible. Once it gets there, it uses cheap, strong beaters such as Nimble Mongoose and Tarmogoyf, which used to be Werebear to win the game as fast as possible. It also uses counterspells in the form of Force of Will and Daze to control the spells played, along with Lightning Bolt for creature removal and direct damage.
