They deleted my first review so thanks Google. The free packs they give you for doing Single Player missions literally contain 2 cards. Laggy AF on mobile. No option to rejoin Ranked Duel after the game crashes. Opponents take 20 years to make a move (*lag + slow play*), no turn timer just an overall timer so they can waste 8* minutes just because. Can't dismantle any "free" (solo mode, rewards, structure deck cards) cards for dust because KoMONEY. What am I gonna do with 6 copies of any card?
