SIF has become incredibly p2w (and also pay to collect) with banners that are only accessible through paid gems. It would have been fine if they had just added better banners with paid gems, but they also made the usual f2p banners worse instead of leaving them as they were before. The game is also filled with bait banners that sound good but are then instantly followed by better ones that give out the same cards with way better rates. 2* just because the game is somewhat fun despite everything
