It does update, but it isn’t perfect. Sometimes it wont update the mana when a 0 cost card enters the graveyard until I play a card >0 cost on the field.
Also when a card enters the grave, it doesn’t update the max.
*The example below is based on already having 2 cards in my graveyard
Example, I have 2/2mana -> play 2 cost card on field and it goes to graveyard immediately -> now I have 1/2mana but I should actually have 1/3mana since new card entered the graveyard.
My main concern was getting the mana working so you do not have to necessarily help me as these are more just bugs that I can tinker out. Your help is always appreciated though.
Thanks for the help!
