RE: MAA - hax - easy win
I would not recommend using the Quicksilver massive damage hack for pvp, because the enemy QS gets it too, and if he goes before your own QS, you will get wiped out.
Instead, use the same method of increasing damage, but apply it to either Loki, Hawkeye (with e-iso) or Captain America (with e-iso). All 3 of them will take first turn just like QS, often before him, and chances of meeting them on the enemy defense is almost 0%, whereas QS you will meet at least 75% of the time in the higher adamantium ratings.
Loki is the best to use, because he can make 2 attack per round (his L9 is a quick action aoe attack)
