I got this idea from the developers vs the builders event, from the mega P.E.K.K.A. I though that if maybe there was a troop that could make one troop like that, It would add much more customization to clash of clans and add a funny way to make troll attacks.
Basicly, what this troop does is sacrifice itself into any troop near it and make it slightly bigger and have better stats. Each costs 1 training space, and improves the targets stats by 0.5% of its current stats, and then its own stats 3x. They can hit both air and ground troops, and when sacrificing itself it stuns the target for 1 second (unstackable) and when the upgraded unit gets hurt it loses 35% of the health it lost in all of the other stats that were upgraded so that you can't put healers on a mega troop and expect it to work out that good. Of course, the 0.5% stacks on things like witches so once it gets high enough it will spawn extra skeletons, and the skeleton's stats will be inproved, too, but only by 10% of the stats and the same thing for anything that can spawn stuff. It also does nothing if it has nothing to upgrade. It starts out with 23 Hitpoints at level one, and its stats given to another troop upgrades the higher the level it is. When the upgraded troop dies, 1/8 of the sprits that went into the troop jumps out and goes to another troop, except this time without the stun and after that unit dies they don't jump out unless an original was used on them. To make it better on any troop, not just heros, it will give them more stats up to the closer the troops cost is up to 5%, but the cost will increase for every spirit and they just give normal stats on heroes. I'm pretty sure supercell won't add this due to the complexity, but if supercell can find a simpler way to use this idea I would love to see it, or maybe someone could post it in the comments, but not much people comment on my ideas.
