Trainers » Devolution Spray | Abilities » Eternal Zone
If I have Eternatus VMAX with "Eternal Zone" Ability in play and I use Devolution Spray Z to devolve one of my benched Darkness type Pokemon to a non-Darkness type Pokemon with enough damage already on the devolved Pokemon to knock it out, is it KO'd before having to reduce my Bench down to 5 Pokemon, or if I discard it to reduce my bench is it not KO'd?
You would discard your Bench down to 5 first, then check for a KO. That means you could discard the newly devolved Pokemon to avoid a KO, even if Eternatus VMAX is the one being devolved!

Abilities » Field Runner | Trainers » Galar Mine
What happens if Cinderace V with the "Field Runner" Ability is in play while Galar Mine is also in play?
Cinderace V would have no Retreat Cost. When effects that increase something like Retreat Cost by a particular amount are stacked on top of effects that make something like Retreat Cost vanish, the vanishing effect takes priority.

Trainers » Mallow & Lana | Attacks » Moongeist Beam
If a Pokemon was attacked with Lunala GX's "Moongeist Beam", does that block Mallow & Lana from healing it?
The first part of Mallow & Lana says to switch your Active Pokemon with one of your Benched Pokemon. When your Pokemon is switched the effect of Moongeist Beam is removed, so then you can heal the Pokemon once it is on the Bench.

Can I use Hyper Potion to heal a Pokemon with less than 120 damage on it or if I have less than 2 Energy attached to it?
You have to heal at least 10 damage to play the card. You must also have at least 2 Energy attached to the Pokemon you're healing; if there are less than 2 Energy attached you cannot use this card.
