Dragon Rider- LMK what y'all think so i can add more to it later

Description- After years of domestication, these Knights have figured out how to tame the mighty dragon. Their secret is a diet of Dark Elixir which has made them smaller, but quicker and just as deadly as their untamed counter-parts.

How it works- The Dragon Rider is a two piece unit. The Dragon and the Knight. Initially airborne, any defense tower targeting the DR automatically attacks the dragon. When the Dragon dies, the DR becomes a terrestrial troop, the Knight. At this point the Knight is left to attack and is subject to defense towers.

This tamed Dragon looks a lot like its counter part but is smaller and quicker, allowing them to take up less space in the training camps. Due to their agileness, the Dragon is able to remain un-detected by seeking air mines.

Knight-

DPS- 80
HP- 350
Fav Target- Anything
Dam Type- Single Target
Targets- Ground
Movement Speed- 20

The Knight's armor is similar to that of the PEKKA, making them vulnerable to Teslas (x1.5 damage). However, the Knight has a slimmer version than that of the PEKKA, in which it is heavy enough to be invulnerable to spring traps without reducing his speed drastically.

Personally I like this idea but think it is too much like the hog rider. I would recommend a different name for the dragon and think it would need to be a bit more expensive (100 DE is almost as cheap as a valk) so i'd go for 250~ DE. Also, I don't think 'agileness' would make something able to avoid a seeking air mine. Minions are just damned small. Let them be hit by air mines.

Would the Knight attack while flying? I worry that would become too OP, kind of like a protected, air PEKKA.

Nice idea but Its a little op and maybe new name suggestions?
