Giant Treant Druid

This deck has Witchwood Apple and Keeper Stalladris to fill your hand, and then cards like Ferocious Howl, Wispering Woods, Bewitched Guardian, and Mountain Giant benefit off of that. Cards like Landscaping, Wispering Woods, Force of Nature, and The Forest’s Aid fill your board, and then you can buff it or drop down some Sea Giants. 

All three “Costs (1) less for ____” cards available to Druid (Mulchmuncher, Sea Giant, and Mountain Giant) shine in this deck. This allows Gloop Sprayer to be played with them on the same turn to get a bunch of huge minions.
