The tomb trap.

Takes up a 2x2 square like a big bomb. Everyone gets one of these starting at th1.
Once activated, the trap takes out one troop no matter the health left. It can knock a barb king or archer queen out. It can also kill a full health pekka or make a golem explode into its golemite counterparts. Or if smaller tier 1 troops get next to it, it will take out one of those whichever is closest to the trap.
Thoughts?

Way too overpowered, just ruins the point of hitpoints. (Well, at least overpowered in war and trophy pushing.) In war and pushing people normally use strong troops, and if they get killed in one hit... That would make defense way too OP. And th1? The tutorial forces you to upgrade to lv2, and all you have at lv 1 is barbs. But anyway, OP.
