Need some advice on building my roster.

[system]

Classic Storm - Lvl 85- 5/5/3
Modern Thor - Lvl 71 5/3/4
Aston. Wolv. - Lvl 44 5/3/5
Modern C. America - Lvl 36 5/4/4
Ragnarok - Lvl 30 2/3
X-force Wolv. - Lvl 30 1/0/0
Invis. Woman - Lvl 30 0/1/0
Marvel NOW! Magneto - Lvl 16 3/3/1
Punisher - Lvl 15 0/1/2
Black Panther - Lvl 15 1/0/1
Daredevil - Lvl 15 1/1/0
Clasic Doctor Doom Lvl 15 1/1
The Hood - Lvl 15 0/1/0
Hulk - Lvl 15 1/0/0
Patch Wolv. Lvl 15 - 0/0/1
Orig. BW Lvl 15 - 0/1/0

Should I go for Thor, Wolverine or Captain America for my next focus?

Cap is nice. Thor is better.

Your roster is really weird in that it seems like you can skip the 2* phase entirely and go right into 3*s. As Dormammu said, go with LazyThor and never look back: he just fits in any team composition. Cap is fine to level after you level LazyThor since his red is a lot better and he has relevant blue ability, ignore A. Wolvie completely: he’s pointless when you have LazyThor around.

Lazy Thor all the way, but if you get the covers try to respec your Cap to 3/5/5. That’ll let the blue and red tiles overwrite any other kind of tile.
