mvc does have alot of lag in this game but u still can get around it. Just keep jumping as fast as u can and block right aways befor his blast attacks. Try to land behind him and either kick him or shoot blasts to build up your energy bar and then attack him with a super blast. if u land in front of him try to kick him or call out your helper. When u face people with alot of lag u have to be ready for a long fight cause alot of your attacks wont go through and u when he hits you the hit will count against you.
