But the thing is Sonic's disadvantage against Wario isn't as detrimental based on the number of Wario's you'll play. Wario has a few bad matchups of his own so you won't see an overwhelming number of Warios leaving Sonic still viable as a tournament character. With MK its different. Partially because of MKs few (if any) disadvantageous matchups you're going to see alot of them at any tournament. So if you play a character that is weak against him you are going to run into him no matter what, and several times.
