Cynder, I challenge you to a duel!
The conditions we'll fight under (Except you want to change anything):
=> Let's start with a 2 v 2, alright?
=> You send first, attack second. (Although I'm fine with a switch)
=> 3 Days DQ time. Enough for you?
=> 40% Damage Cap
=> Banned Moves: Pain Split + every non-status inflicting regeneration move like Slack off, or synthesis. If used, nothing will happen, due to the strange surroundings of the arena. (Don't ask. This is legit. >: D)
The arena, let's try something new, shall we? (Ergh, if I'm allowed to just throw something new in, we might as well stick with Indigo Plateau)
The Great Lake
A mysterious lake in the middle of a forest. It fills the entire battlefield and the combatants are standing on several lily pads of enormous size!
Pokemon of gigantic proportions might get into trouble here, wiggling all around the fighting-"ground". Might also be an advantage, who knows?
However, except for additional maneuverability, water pokemon don't have any major advantages.
