I had my Gardevoir first with synchronize that I was using to catch Sligoo, and so I did. It was a modest one. I went to the nearby town that was raining, and leveled it up to evolve. Its nature is sap sipper, however... should I keep it, or go for a different ability?
What's its other possible ability?
I hate going up against sap sipper personally as they're immune to leech seed.
