Which PvP teamc can I beat?

Hi, sorry for posting here, but I am not able to post in any other forums. I am currently on the 3star covers hunt, my grinding team for PvP consisting of 2x Thor 2*, Storm 2*, Magneto 2*, Wolverine 2* and Gamora 3x, all at level 94.

Whenever I play PvP events, i reach about 300-400 points, and then have to choose wisely, who I can beat. I usualy only go against the featured character with Storm 2* and Magneto 2*, cause those I can beat. Is there any other easy combinations, that I am affraid of, but are relatively easy? Its hard for me to be top 100 as in to get the good covers unless I win more fights against lvl 94 teams and on.

Can you, please, help me?

Thank you
