Well, [here's a card guide for beginners](https://www.reddit.com/r/future_fight/comments/8hotwk/updated_guide_to_comic_cards_for_mff_v40/). It's a bit outdated but it still works.
If it helps, the premium cards from Ragna Loki, Ragna Thor, and BP are awesome for F2P.
Thanks a lot. I appreciate. I'll go through it as soon as possible.
Already got Thor IW y'day.
So Ragna Loki would be my best bet for now.
BP uni and a T2 ticket (not even mega( for 3k crystals is a little outrageous for me considering he's bad at T2.
Psylocke or Magneto would replace that.
