Hearthpwn

Pretty straight foward, mulligan for murlocs, and try to play on curve for the first few turn. Then try to go for concecration if you are playing vs aggro, or equality if you already have a concecration or the enemy have huge minions. Keep in mind that 2 of your murlocs have charge, so abuse them to keep the board clear and mitigate as much dmg as possible. If you have 4+ murlocs dead, just survive till 10. Heal, taunt up or threaten the board with doomsayer. If you can't OTK with your turn 10 Anyfin, use your murloc to clear the board until your next Anyfin.

Note: Since I'm a F2P scrub, I don't own Wickerflame, but he would probably be a good switch from sludge belcher, also tank about 2 hits but heals you for 4 in the process. Possibly more if left alive.
