Brann and/or Murkeye

In the midgame, generate a lot of murlocs using Brann and Primalfin Murloc plus trigger battlecry effects like Rylak or Murkeye. You can use Bream Counter Bassgill Choral Mrglglrs to stabilize. In the endgame, you always want to keep Murkys and Murkeyes to scale the fastest. You should be able to generate these with Primalfin lookout.
