>flying type, meaning it can attack safely out of the lions' reach from the air>gets recycle, meaning that with a leppa berry, it'll never run out of pp>just spam special attacks and recycle as neededThe only way I could potentially see the lions beating Drifblim is for them to climb the increasingly high pile of dead lions to the point in the atmosphere where Drifblim's density becomes greater than the air around it, assuming the lions can even breathe that far up, that the pile covers a great area which Driflblim cannot easily avoid or drift away from, and that Drifblim's flight is bound by physics and not supernatural (we'll get to that). There's other flying types that get recycle (Drifloon, Delibird Noctowl line, and Arceus) but I picked Drifblim because it's fully evolved, its flight isn't reliant on flapping and it's not a god. Additionally, unburden makes it very fast without the berry, or if it has aftermath and somehow faints or dies, it will take a good amount of lions with it. Flare boost, if activated, will kill it before it kills all the lions, so it's not a good choice.
But the best part comes from the Pokedex, if it's accurate. Drifblim is stated to be powered by the souls of those it carries away, and it takes them to the afterlife. I take this to mean Drifblim grows in power with each kill, allowing it, if we're being conservative, to sustain itself as it methodically kills all the lions, or, more likely, reach Ultra Blimstinct.
Checkmate lions.
