Maxed Giant Bombs - Immensely help with hogs
Bombs - Don't really need to be maxed, but they help a bit to kill tier 1 troops when paired next to each other inside a base
Air Mines - Already kill Minions(at any level) in 1 hit; the blast radius could be a huge help though [Just don't keep them at Lv1/2]
Seeking Mines - Kill those Drags quick. Pointless against Mass Loon Raids though
Springs Traps - Hopefully will be upgrade-able
