Dark healer/wizard

Another one of my ideas, is to have a new dark troop. in the higher up levels healers become useless with those multiple and powerful air defenses making it used heavily in lower th5 and 6 but when you go to th 8 and 9, it is almost unused.I was thinking about a dark troop alternative to this healer. please keep in mind that this idea i have is still in its early stages and please don't be 100% against it if you feel it's too overpowering or useless, just comment below if think there should be any changes. This idea i have i think should look and working like a wizard. The troop (please comment a good name for it) would be a ground unit instead of a flying one making it not vulnerable to air defenses and putting behind another the troop it's healing keeps it less likely to get destroyed. A wizards send a concentrated blast fireball towards it enemy doing incredible damage, this healing wizard will do the same, but unlike the wizard it wont do splash damage to keep it from being overpowering. The wizards have few hitpoints for their housing space this will also be kept the same for this troop. This troop doesnt have favorite target to heal and will be able to heal both ground and air troops, with the exception of a healer. No that would just be the most impossible to destroy army nightmare of clash of clans because then everyone will use ghetto healer giant combo, but even worse, the healers would be backed up with this troop. The system will not work the other way around either, this troop cannot receive healing from healer or each other, just like healers it can only be healed with a heal spell. However i still think it would be nice to have air capability so that it would work on dragons as their are only a couple this will keep the dragon strong especially if it turns away from an archer tower or airdefense. The ground troops that this will work well would be the pekka and gollem.
