Bug? Decidueye Vs Regidrago Vstar
I think the game is registering the selected attack as coming from the Pokemon in the discard. Decidueye's ability should prevent all damage from v, Vstar, and VMAX. But for Regidrago vstar (and Mew VMAX) it doesn't seem to work. Everything I can find for rulings says it should prevent the damage but it's not.
