Honestly only wanted to rate this app just to say to everyone that this isnt your childhood Yu-Gi-Oh card game. It is a different game entirely in some aspects but given the chance it will definitely meet or surpass your expectations. The fact of there only being 3 of each card spaces on your field is intentional due to the game being based around modern dueling(speed dueling). The most any card costs for tribute summon is 3. Also JS God Cards immunity effect only works upon initial summon.
