Gold Troops

My idea is a troop that takes gold to train. It would require a new barracks.
Troop ideas.
Lvl1 barracks: Dwarf. It would be a little stronger than the barbarian but pretty similar. Its attack would be a melee attack with an axe.
Ability: it resits arrows from archers, but Like the pekka is suseptable to the tesla
Training cost 100 gold
Training time 45s

Lvl2: spider: a quick moving, light weight automation. It would attack with rapid melee attacks.
Training cost 150 gold
Training time 1m30s

Help me out with more specs!

I already posted a spider that slows enemies and defense with webs.
