Dark Elixer New Troop Recommendations

Here's a few good ideas (I believe) for some new Dark Troops in future updates
1. Dark Chimera: a three headed dark dragon, with each head spewing forth a different attack... Fire, electricity, freeze, poison are a few that come to mind.
2. Dark Troll: here's a creepy critter: a troll summoned from dark elixer that climbs walls and goes only for resources.
3. Dark Spectre: a semi-ethereal creature that envelops enemy troops and sucks the life out of them. Or defenses.
