Since I don't believe this has been mentioned in the thread yet, how viable would Steel Pursuit Scizor be? Scizor strikes me as a good user of Steel Pursuit as thanks to the fact that it's blessed with a powerful priority move in Technician Bullet Punch it forces out most Pokémon weak to the move, even those that would be able to outspeed and deal significant damage to it otherwise (think Mega Diancie). Steel Pursuit capitalizes on the switches that Bullet Punch forces as a result, so it's definitely good on paper... but what I'm wondering is whether it'd be worth the opportunity cost of running it over a move that allows Scizor to circumvent its standard checks with more ease, like Ground Quick Attack or something. Anyone have thoughts on this?
(I suppose it really depends on whether your team needs a reliable way to eliminate Steel-weak Pokémon like Weavile and most Fairies, but I figured I'd ask for input on this nonetheless.)
Steel Pursuit Metagross actually hits harder, as does Escavalier. Not that Steel Pursuit Scizor is automatically bad or anything, but these two are worth keeping in mind. Bisharp is 5 Attack behind Scizor with access to Sucker Punch, too, giving it a stronger (though less reliable) priority move to threaten the foe with. In general STAB Pursuit looks like an incredible way to revenge key Pokemon.
In fact, have a list of all non-pure Dark Pursuit Pokemon with more than 100 Attack that are legal.
Aerodactyl: Rock and Flying Pursuit both offer exceptional coverage, and with Mega Aerodactyl you get Tough Claws support. Bug, Grass, and Fighting types can't run from Flying Pursuit, while Flying, Bug, Fire, and Ice types can't run from Rock Pursuit.
Rampardos, Tyranitar: 165 Attack with the potential for a Band or the like. Scary stuff.
252+ Atk Choice Band Mold Breaker Rampardos Pursuit (Rock 80 BP) vs. 4 HP / 252+ Def Eviolite Chansey: 340-402 (52.9 - 62.6%) -- guaranteed 2HKO
Yeah Chansey, have fun running.
And of course it has Head Smash!
252+ Atk Choice Band Mold Breaker Rampardos Head Smash vs. 4 HP / 252+ Def Eviolite Chansey: 637-751 (99.2 - 116.9%) -- 93.8% chance to OHKO
Nasty 50/50 there.
Oh and I guess there's Rock Pursuit Tyranitar too. It's already used as a Pursuit trapper, so it's definitely worth noting.
Hitmonchan, Hitmonlee: Fighting type Pursuit could be neat for breaking Steel walls, though I'd argue there's better options.
Toxicroak: Fighting or Poison Pursuit trapping. I have doubts anyone will run this for either of those, but there's potential -if for some reason you just
hate Ludicolo, Poison Pursuit Dry Skin Toxicroak is a pretty solid answer.
Bouffalant, Slaking, Snorlax, Stoutland, Zangoose: Hidden Power doesn't work this way. If it did, it probably still wouldn't make sense -you'd probably be better off setting your Pursuit to punish some Pokemon your team hates. (eg Fire Pursuit for Scizor)
Mega Altaria, Druddigon: Since you can't have Fairy Pursuit and you can't have Normal Pursuit to get it Pixilated, I'm lumping it in with Druddigon. I'm not sure what the
use of Dragon Pursuit is, though, beyond being STAB. Admittedly both Pokemon hit fairly hard, but only Mega Altaria is likely to be switching into and scaring out Dragons, and I suspect it has better things to do with its moveslots.
Banette/Mega Banette: Like Rampardos, Mega Banette has 165 Attack to work with, though unlike Rampardos it doesn't get to carry a Choice Band or other item to bolster that. Ghost Pursuit is basically Dark Pursuit, only replace Fighting and Fairy resisting it with Normal being immune to it. Given how Pursuit-trapping gets
used, this isn't necessarily much of a disadvantage. Main flaw is that you leave Mega Banette with Shadow Claw as
still its best STAB, when it would really like to convert Return or something. In practice you're probably better off using classic Pursuit-trappers like Bisharp, or some of the new Pursuit trappers.
Bisharp: One of the stronger Steel Pursuit trappers around, and has the threatening combination of Pursuit+Sucker Punch. Has the key flaw that it doesn't actually resist Fairy, and is fairly fragile. Mega Altaria, for instance, is liable to have Dragon Danced and promptly kill you rather than switch in fear... unless it thinks you're planning on Steel Sucker Punching it, of course.
Mega Beedrill: Poison and Bug are both depressing attacking types, but with monstrous Attack and an Adaptability boost, Bug Pursuit can still be used as a way to murder key Dark, Psychic, and Grass threats. Main problem is that Mega Beedrill much prefers U-Turning out of everything. Might prefer Bug Knock Off, too. Maybe.
Dodrio, Staraptor, Honchkrow: Flying Pursuit-trapping! (Also Honchkrow can still do Dark) Still just as useful as when I described it on Mega Aerodactyl, only replace Tough Claws with item access.
Krookodile: The best Ground Pursuit trapper in the meta. Given that one of Ground's key flaws is that it's easy to switch into it -just get a Flying type or Levitator- this has some amazing potential to utterly destroy various Electric, Ground, Rock, Steel, and Poison types that would normally simply switch out of Krookodile with little fear. You also have Moxie to turn that into an instant +1, potentially letting you break past whatever was
trying to switch into you!
Doublade: Steel and Ghost Pursuit trapping. Is it worth it? Honestly, probably not. 110 Attack is nice, but you're carrying Eviolite, come on.
Floatzel: The best Water Pursuit Trapper around. (What, you think Pelipper is viable?) Notable for that alone, as Water is a pretty sweet attacking type. Might give Floatzel an actual niche in the meta?
Metagross: Hardest-hitting Psychic Pursuit trapper you've got. Also provides solid Steel Pursuit trapping which, if we're honest, is the much more likely reason to be running it. Still, if there
is a Poison type giving your team trouble, Psychic Pursuit Metagross could be good.
Heracross, Mega Heracross: Fighting or Bug Pursuit trapping. Like Krookodile, note that regular Heracross has Moxie. As such, you can grab a Pursuit kill and
then Mega Evolve and sweep. Maybe.
Escavalier, Scizor: Steel or Bug Pursuit trapping. Already been covered by other people.
Scyther: Yes, really. I'm not sure
why you'd use it as a Pursuit trapper in Custom Power, but there you go.
Weavile: Best Ice Pursuit trapper... only one with STAB, for one. Ice is, of course, an incredible attacking type, so it makes for a pretty terrifying Pursuit.
Mega Sceptile: Yeeeaaah I dunno. To be fair, your only other STAB Grass Pursuit options are Serperior and
Parasect... I
guess Pursuit Mega Sceptile might end up being a thing?
