Great strategy but I don't have harpie dancer and since I'm f2p, I don't intend to search a box for one card...
Is there a replacement for harpie dancer?
Just use this deck, give your guardian statue with the mystic box and leave one card in your deck, then use magical blast-wonder balloons combo every turn, you get like 15-20 summons per duel
I just unlocked the mat with the deck above (the one that says (Rainbo). I suggest everyone to run that one if you don't have Harpie Dancer or any other card from a box you haven't had the chance to open.
