Take Chests with Worgen and commit more units if needed. Ritual of Rime to defend against air, especially Gargoyle. Whelp Eggs on top of enemy units to melt them. SAFE Pilot also good to take out squishy targets and deal elemental damage. Quillboar can deal with Elemental casters. Earth Elemental is a good tank vs physical damage(includes towers).
