Brainstorming fresh mechanics.
How about we try thinking up some mechanics to really freshen up gameplay. Something like instants, spell cards that can be played durring the AI's turn to interrupt or alter the cards played. This would add another level of strategy and would further engage players durring the AI's turn. They could have triggers like when an opponent casts a card or even when an opponent makes a match five. Something like, this card can be played when an opponent plays a match five, your opponent's turn immediately ends.
