I would like to suggest that an option in ur that decides an automatic win or lose.
in the final round.., player X has 7 life 9 pillz while player Y has 5 and 4 pills life. player X last card is a 5* 8 power 6 damage no ability while player Y card is a 2* 5 power 4 damage no ability. both cards has no bonus activated. with this example player X will surely win.
so why not let the system decide that player X already won skip the final round before player X lags or accidentally click no pills and make fun of himself.
I think the player with Greem still has the right to chose the card. part of his strategy. there could be times where attack manipulators, high powered card, low star cards still forces the opponent to pill an extra instead of using that pill for a valued fury.although, i see know reason for a winning player to be stalling unless he just wants to or blew his chances of winning.
