ok i think it be cool for there to be a card like tough but not to boost attacks but to boost heal spells, and yes i know there are spells you can use to boost them but i think it be cool to have heal spells boosted and it dont have to be a lot i mean if it was only +50 it still be so cool but its all up to you:)
i know but thats a spell you have to cast like a blade or such but i think it be cool to have a card like tough that you can "enchant" a heal spell to boost it
