So how would the battles work if WTP was defending against three attackers? That's only two more attackers than defenders, so these rules wouldn't apply.
Alright. Here's what I'm thinking. This would only apply for situations where the attacking team has three or more attackers than the defenders, who number two or less. Otherwise, it will remain the same.
1) This only applies to the defender(s).
2) Health carries over, status do not.
3) At the end of each battle, any Pokémon KOed, will be revived at 20% health.
3) At the end of each battle, for every number of attackers that the defender still has to face, the defender's Pokémon's health will be increased by 10% for each one.
Ex.) WTP has to defend against four battlers. He defeats the first one and his Pokémon are at: A] 62% | B] 23% | C] 45% | D] 0%
Following the rules above, since WTP has three attackers left to face, each of his Pokémon will gain 30%. So the new totals will look like this:
A] 92% | B] 53% | C] 75% | D] 50%
The rules in the first post would apply here.
