Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
When a Pokemon faints, the opposing Pokemon replaces its current ability with the fainted Pokemon's and gains its last-used move in a new slot. These changes last the entire match. If a Pokemon faints before using a move during the match, no move is gained by the opponent.
Any fully evolved Pokemon can mega evolve using a megastone. When mega evolving, the Pokemon recieves the same stat boosts reductions and gains the same abilities as the original Pokemon (that the mega stone was meant for) do when mega evolving.
Standard STABmons set in Ubers with new changes like base forms being able to transfer moves to their alternate forms and mega evolutions, transferring moves from types they had in an old gen and unreleased moves being usable.
Swaps the highest stat and lowest stat of each Pokemon. If there are multiple highest and lowest (so if both Attack and Defense are highest), they are switched together.
Votes frmo after this time do not count. Also, I hope you guys read the rules because starting from this iteration, votes from people with less than 5 forum posts do not count. So, rip lurkers :(
