Since this is the exact same combo deck we run, the matchup is a race to assemble Broodscale plus Blade of the Bloodchief first while disrupting the opponent's copy. Trinisphere taxes their cheap interaction and artifact-based answers (Vexing Bauble, Haywire Mite, Soul-Guide Lantern) without slowing our own lands-based mana much. Pithing Needle can name Blade of the Bloodchief to turn off their equip ability and stall their loop, while a second Vexing Bauble counters any free/zero-cost disruption they try to use against our combo. We trim our own Blade copies since two live copies is redundant when the first one usually wins, and cut the clunkiest top-end (Emrakul, Sire of Seven Deaths) since this matchup is decided by the combo, not by big creatures.
