Summoner/Spell Caster:Dark Elixir Troop Idea!

I think that Clash of Clans should really have a troop that summons spells. The spell caster or summoner could spawn levels 1, 2, 3 or 4 spells depending on the level of the troop. It would have not much hit points, like a healer for example. The Spell Caster would have a staff which would be his basic attack, hitting things with his staff:). He would cast spells such as a heal spell on the area of the player's choice. Al the player would do is click on the spell Caster icon in the attacking screen and tap where he would place the spell. He would be able to cast a spell every few seconds or so. The Spell Caster would be a ground troop with not that much speed, perhaps the same as a dragon? People could use the spell caster to their advantage in the go wipe strategy where the golems take the hits and the other troops destroy, the spell caster could provide backup to the other troops in trouble. Players could defend this new troop with their long range defenses. The spell caster wouldn't be able to completely destroy because of it's low sped and hit points. However it would cost around 100-200 dark elixir per troop. Thanks for reading my new troop idea! I hope you consider creating this troop.
