Adding field to calculations

[Skylander591]

I know it's been a fairly long while since this project seems to have had any updates, but I've been using it recently for my first playthrough of the game.

I was wondering if it would be possible to add in the option of being able to input the cards on your field as well (instead of having to replace one of the cards that's in your hand to see to see fusions with that card or cards.)
