I kinda got bored of reading every post after a few pages, But someone was talking about the idea of a pokemon which removes weather when it switches in, I don't know if anyone's mentioned this yet but Golduck does just that.
Anyway, With that aside what about an ability for a pokemon that when it switches in, Your opponent's pokemon takes the entry hazard damage? I'm aware that putting it on something thats 4X weak to rock is kinda stupid, Especially if that pokemon is extremely capable of sweeping. But If it was put on something with a mediocre BST it could be useful, Although that might be slightly broken..
Now I think about it, Something with such an ability will switch in - Opponent takes SR Damage, Spike Damage, and gets poisoned due to toxic spikes. That is quite alot of damage, Especially if this pokemon that is switching in has the potential to finish off what it's switched in to.
Hmm... On the other hand it is quite good, It could stop people spamming up SR and that, It makes it so there's a price to pay for setting up all those rocks, This pokemon could switch in and completely screw you over.
Well, I guess I'd have to think about this some more, It could turn out to be completely broken... Anyone else have any thoughts on this?
