Contrary doesn't add boosts or anything, it just inverts them *if they're affecting the pokemon with contrary*What happens if malamar uses Topsy Turvy at +1 atk +1 def? Does it still become -1 atk -1 def or does it become +3 atk +3 def due to contrary?
If Topsy Turvy was used on something at +1/+1 it'd be changed to -1/-1. If Topsy Turvy was used on, like, a +1/+1 Contrary Spinda I'm guessing it'd just flip back to +1/-1
