I remember playing this obsessivley (but f2p) in middle school and then my phone was stolen and my dad gave me his old iPhone and then I couldn't play this anymore and I didn't miss it at all after like a week
Weirdly fun for a pay2win mobile card game. There were just better versions of the cards you had, which you needed to beat the campaign. Would have been cool if it were made as a pure singleplayer experience without the grind and the in-app-purchases.
