Insane card for Slowking

Kyurem and then this on evolution pokemon can be really spicy.

Edit: This can be really useful against Beedrill, Garchomp, Greninja, Dragapult, Starmie, Hydrapple, it's a 2 attack combo for when you couldn't kyurem in time (maybe you went second and they had rare candy for example, or you bricked early game).
