General Strategy:

Generate card advantage through geomancer's ability, play value minions and sites that either generate minions or desserts for giantess or ping off wards, use spells to buff up your minions, and create surprise burst damage using Blaze, Blaze of Glory, harpyon Urge and Onslaught. Finish off with Major Explosion or Craterize.
