As for the combo: no.Would said elemental punch combo take correspondingly less energy?
EDIT: I assume that Spiky-Eared Pichu's special moves are usable by Pichu here?
But yes to Spiky-Eared Pichu's pain split.
I would say you could ask a pokémon to hold bide, yeah. It would probably require extra energy, however.Normally one would be able to command their Pokemon to wait before attacking, but I'm wondering if this is the case with Bide? I'm pretty sure the +1 priority doesn't apply to the turn it releases, but I have doubts about a Pokemon being able to hold in all that damage/energy/whatever for that long.
Yup.Can spite affect normal types?
