PVP Roster advice

Unknown

Hello, I am really close to making a transition to full time PVP, with the knowledge that I can level up several 3* now to 166. I just am not sure which will be the best for starting out.

Below is my team covers and their current build.

Various low cover 4*
4* X-Force: 2/4/1, lvl 103 (might buy an extra black)
3* Patch: 1/4/5, currently lvl 119
3* Cap: 4/4/5, currently lvl 119 (switching him to 3/5/5 when i get a red cover)
3* BP: 5/5/3, currently lvl 119 (trying to get 2 more black covers to make him 5/3/5)
3* Blade: 4/3/4, lvl 113
3* Hulk: 3/3/3, lvl 107
3* GSBW: 3/3/3, lvl 103
3* Mystique: 3/4/2, lvl 103
3* Colossus: 4/2/2, lvl 102
3* Deadpool: 4/1/5, lvl 101
3* Falcon: 2/5/2, lvl 101
3* Spidey: 2/2/4, lvl 101
3* Cap Marvel: 4/4/4, lvl 94
3* doc oc: 5/2/3, lvl 90
3* Dr Doom: 3/3/2, lvl 86
3* Torch: 3/2/2
3* Daken: 3/2/1
3* Thor: 2/2/4

Full 2* max level roster

Who should I level to be competitive in PVP? I originally was thinking BP, Patch, Captain america to level max.. but blade is also looking pretty enticing, though his max right now is only lvl 140. It seems to me that i may not have a full roster of max yet, but close. Thanks for any help!
