I’d suggest you read this thread, which has a lot of good ideas on how best to use Wilbur:
Personally I don’t like him on defense—which is to say, I love finding him on defense. I can set up a jujitsu move to turn the special against the other side (e.g. cast any Ramming Pulverizer) or even my own Wilbur, carefully timed.
Timing on Wilbur is everything, which means he’s mostly best on offense.
