I found the best way to take care of darkrai was to get breloom's toxic orb and poison heal activated and once darkrai was taunted, false swiped and paralyzed, then send back in breloom as it laughs at the non effective faint attack and all that's left to do is capture darkrai. It worked like a charm for the 3 darkrais I caught across 3 games
