I think he's easy to beat. No tips, just play the game normally.
com'on he/she is obviously new to strikers, be Mario with toad, koopa & hammer bro I leant to play as that team a year ago.
now that im an Exspert non-cheap player i STILL choose Mario & koopa but replaced toad & hammer bro with 2 boo's(not for cheapness but for passing), so they are a realy sold team,
NOTE: dont try the 2-Boo koopa & Mario team untill you've gotten the ins & outs of MSC.
