In any Game of pokemon there are certain things that just make tournaments gay, and any PvP for that matter.
I know i asked about this in chat 1 day but im gonna make a bigger deal about this.
In a PvP battle(we aren't talking about NPC's so chill questers) you should not be allowed to use potions, full heals, any battle items, nothing. It is how the game is made if you ever battled a friend on gen1, (I think for 2-4 too) and it will be gay, tedious, and just not very poke-ish to let this occur. so im extremely pleased that there are no legendaries because for obvious reasons, but there also should be no items(hold items are allowed) in PvP.

I know that Smeargle isnt the best Pokemon challengewise but i just liked the name of this quest

Smeargle can be used very effectively in battles though considering it learns Sketch which is like any moves, so I was thinking a tough high level (Elite, they would call it in WoW) Smeargle with a tough moveset
