Please look at the Screenshots Glutonious Slime is Dead, however, I have still control over it and I can cast spells.
It seem having dies due to Live to Labor.
That is pretty funny. I wonder if it has something to do with the enemy Elf Barbarian? Assuming there is a trigger to end a creature’s turn if it dies on its own turn, I bet the Elf Barbarian is preventing it when it really shouldn’t.
