new heros and traps and troops

what about a hero that is a skeleton knight and he has a ability to summon smaller skeleton knights that are as big as barbarians(they would also be good troops) and he is as big as a barbarian king and does the same damage another would be a water serpent and does double damage on dragons but is weak against lightning spells but he is stationary so he can only be used as defense but he can attack air and ground and he stays in a small pond that can only be crossed after he is knocked out and only by giants barbarian kings and golems , the new traps would be dark elixar the first one is a vortex trap that only gets ground troops and it has a 6 tile radius and does 400 damage but double damage on dark troops the other one is a lava pit and it has a 4 tile radius and does 300 damage and they have to be rearmed with dark elixar, a troop could be the skeleton knight(a dark barbarian that is a little faster and stronger ) or a poisoner the opposite of a healer that poison heros when you attack and after they die the heros they poisoned take 200 damage but do 50 regular damage
