Muckmorpher Shaman

Spirit of the Frog to chain through your deck

TONS of healthgain and removal with Zilliax, Walking Fountain and Muckmorpher

Eventually combo with Eureka!, Malygos and 1 mana spells

You can use Eureka! on a Walking Fountain for turn 6 removal + heal against aggro

Rockbiter Weapon is a 2 cost spell to chain with the spirit, but has awesome synergy with walking fountain too!
