WBR is an aggressive creature deck with efficient threats (Iron-Shield Elf, Marauding Mako, Casey Jones) but relatively little hard removal outside Requiting Hex and Erode, so this becomes a race we want to win with maximum damage output. Dreadmaw's Ire adds a big trample buff to our attackers and can punish any incidental artifacts they bring in postboard. Full Bore gives explosive one-turn damage boosts, including trample and haste if the target creature was cast for its warp cost, to close the race before their board stabilizes. We trim the evasion-granting Pym Particles and clunky utility lands, since raw damage output matters more than unblockability in this straightforward race.
