I use event match # 51 as a warm up... it helps.. if i dont do that then its 2 comps on lvl 9 on a team against me. and a third agains me and them... that is a much better work out.
i would have to agree on the person against person thing... if the other person can be a challenge... if not then you have to give him some cps to pick up his slack... now that makes it interesting !
once i am warm i play three random people lvl 9 on a team against me... That is the only challenge i have found since i lost to Doctor Quivorkian... Just Try it... here i will pick for you this team if unbelievable Samus, Link, and Capt. Faclon. I dare you to try...
you will find a great challenge. then after that continue to just let it pick chars at random, you will see that any combo of three chars on lvl 9 on a team against you will kick your @$$
