With four 2-attack minions on the board, drop Electra Stormsurge and Bloodlust for the one-turn kill (32 damage). Or copy Rockbiter Weapon and swing for 16 with Doomhammer.
I tried this with murlocs but they were too weak and could never maintain a board presence, so I decided to go the more typical aggro route with Knife Juggler. Mechs are somewhat annoying when a bunch of Goblin Bomb get summoned and magnetized with Bronze Gatekeeper.
