Looking at town hall 11 with lighting weather type.
I like it to have quick sand traps
laser Cannons that can shoot laser beams that can shoot multiple troops in a row .
archer tower 14 that can shoot fast an in multiple directions and have lightning stun ability troops can't move for a couple of seconds
wizards tower withs two wizards on tops an they shoot lava beams heal uneffective
healer can heal another healer and create it own heal spell .
I have more ideas Hidden Tesla I Tesla last the HiddenLevel 9 is called the Tesla Fan now it can shoot two bolts
now also when troops are close it spins creating a fan lightning ring causing even more damage
Also I was thinking hidden Tesla level 10 for townhall 12 base off snow but theTesla can teleport anywhere a Tesla has destroyed but we can wait off that.
