Say you're playing against an opponent with no DMC (eg 442) so you use an AMC (eg ND). Your AMC is exploiting the space and having a good game so your oppo put a DMC to stop him and change formation (eg 4132 wide). What would you do in this scenario?

1) sub your AMC for a MC or ST
2) keep it as it is
3) pull or push your AMC to play as MC or ST
