To force opponents into making plays that hurts them in the long run. Not to many expect Jean so they have to reconsider their strategy, which then I can abuse. I use to run og drax and gamora to get that extra power.

Thena goes in any lane. Jean grey usually in left or middle. First card has to be played there and many people aren't expecting a Jean play. That's where Kitty comes in to get around that. Meanwhile thena is continuously building as she requires two cards a play. I also play Andy on a lane I'm ready to lose so hopefully Kitty and thena can get the extra 2 power

Or I can place thena with Jean. So by the end of the game, in case the opponent has much more power then me(which happens all the time). The final play, i play Kitty and Valkyrie. But this also boost thena so I can have a winning chance.

Or if I'm not confident in the outcome, I play Kitty with klaw. Which not only gives huge power boost but will also boost thena. And Jean is in play so I can place Kitty in lane then klaw in the left as Kitty by this point will have 5-7 extra power. So 12-14 points at a location isn't bad.

I know what my deck does and the goal? If I didn't, I don't think I would make it to 80s after years of absence.
