Had a belter of a match online last night. I was 6-1 down with 2 minutes left on the clock. A couple of hyper strikes and 2 late Toad goals gave me the winner.
It's actually pretty tough to get a good balance in your side. I go with Toad up top, Wario, Yoshi and then a full strength Bowser at the back.
One thing I find difficult is timing the dodge well. Online most people I play seem to dodge a lot of tackles and get the speed to break away and slot home.
