Even a Pokémon with a boosting move can't have an easy time? So it was unpredictable and horrifyingly bulky? That's insane and hard to beat, anyone would have a problem.
It was quick? And bulky too? But this was before it got Thick Fat, right? Yeah but Sleep Powder has shoddy accuracy anyway, if it hit that's great for you, bit otherwise if it doesn't...bad, very bad. Such as Scyther? That makes sense, after all once you've beaten a key factor of the core, it'll fall apart pretty fast.
But it doesn't have enough bulk to use it if it had that anyway.
So Arcanine was good for being bulky and a healing move, Darmanitan had it's high attack, and what did Victini have?
Same here. XD
