Mine's unaware and magic bounce You know no matter how many stat change there is, u have nothing to worry :). Magic bounce, I love tricking those field hazard setters. Lol. Anyways I love Gale wings too. .
Multiscale I love using Dragonite in OU and Lugia in Ubers Dragonite hits so hard and Lugia eats everything up
The best ability according to me is Download. It can make a mixed sweeper into an even powerful Phy/Sp sweeper.Alas only Genesect and Porygon family gets it.It should've been distributed to many more.
I guess the ability I like the most is Prankster. Prankster Pokémon are pretty fun to use! Effect Spore is also good, if a little clutch. Flower Gift is great but should be given to something more useful, or made better >:I
Competitive I love using that ability on my Milotic. With that 2 stage boost to Special Attack plus using the move Scald and it's 30% chance to burn the target makes it a lovely threat.
