Okay, since my last battle against danmantincan was a bit haxxy, I propose a rematch!
1v1 singles (duh)
3 day DQ
0 recovers/3 chills
Arena: A square platform over a sea of toxic waste
The platform is about 50 feet by 50 feet, and roughly 1 foot thick, discouraging seismic moves such as Earthquake and Magnitude, as well as Dig. Ten feet below is a sea of toxic waste. Pokemon can be knocked into the poison, with damage dealt/healed upon landing as follows (Pokemon are automatically teleported back to the platform after the round):
10 damage to Pokemon that are hit super effectively by Poison
5 damage to Pokemon that take neutral damage from Poison
2 damage to Pokemon that 2x resist Poison
1 damage to Pokemon that 4x resist Poison
0 damage to Flying-type, Steel-type, and Levitating Pokemon
+5 health to part-Poison-type Pokemon
+10 health to pure Poison-type Pokemon
In addition, to all Pokemon that take damage from the poison, there is a 20% chance of being poisoned, plus a 10% chance of inflicting Toxic poison. Pokemon can voluntarily jump into the poison at the beginning of the round to heal/avoid all attacks during that round, but they will still take damage, if applicable, and that Pokemon cannot use any moves at all. This can only be done twice per Trainer.
How's that for hazardous?
