Dark elexir troop ideas

Demon-dodges every 3rd attack from defences and every 2nd from reinforcement troops-melee sword
Sage-boosts the attack damage and attack speed of allied troops-ranged staff
Rogue-killing a unit or structure heals the rogue-for a percentage deepening on the level of the defence/troop and the level of the rogue-melee dagger
Cavalier-2x damage to hero's and increased movement speed-melee lance
Yeti-if the yeti attacks a troop or defence the attack speed is slower than usual while the yeti is attacking the unit-ranged snowballs

Carrier-a ram that knocks down walls and can hold 10 housing space worth of units the ram will try and get as close to the middle of the base as possible once the carrier has been defeated the 10 housing space worth of troops appear out of the carrier into the battle with full hp
