Fundance was wondering if Grip Claw and Heal Block would work well in conjunction.
The only available user of Infestation AND Heal Block was Reuniclus.
Also, why ISN'T Reuniclus a viable user of a trapping move?
I tested a Bold/Lefties Reuniclus set with CM/Recover/Infestation/Psyshock and found it to not be very effective. With how bulky he was last gen I thought he might be able to abuse Infestation, but with how physically-centered the metagame is this time around, it didn't get many opportunities to set up, and RARELY if ever was able to trap a Special attacker to set up CM on. Even if he did, the opponent would just switch out after it runs out and bring in CB Ttar or something.
As for the Assault Vest/Regenerator set, I can't believe that it would be any more effective especially since 1) it's vulnerable to Toxic thanks to lack of Magic Guard, and 2) can't use Recover because of Assault Vest. Goodra does the whole Infestation/Assault Vest trapping thing almost 100% better due to better typing and Special bulk. Reuniclus pretty much NEEDS Recover in order to make itself not 100% outclassed by Goodra, so Regenerator and Assault Vest pretty much deprive it of both things that it NEEDS to be successful. And, as I stated, even when it had most of those things in its favor it still didn't work that well beyond the surprise factor.
Now, I'm not terribly creative myself, so I'm not saying that just because it didn't work for me, someone else can't come up with something better. I'm open to new ideas with Reuniclus' Infestation, but please try to make an effort to test these sets to see if they're any good at some point when proposing them.
IMO though the best thing Reuni can do this gen is a straightforward bulky offensive set with LO 3 attacks + Recover. Regenerator is pretty bad on Reuniclus in general, since it's basically 100% outclassed by the combination of Magic Guard and Recover.
EDIT To cite a more effective iteration of the trapper set:
Gastrodon @ Leftovers
Ability: Storm Drain
EVs: 252 HP / 252 Def / 4 SDef
Relaxed Nature
- Recover
- Scald
- Infestation
- Ice Beam
I like it, especially because burns are common and freeze can happen.
This has become my normal gastrodon set, trapping pokemon that gastrodon can wall with infestation works great.
Gastrodon's been mentioned before, I think, though I dunno if this exact set was mentioned.
The trap that I think a lot of people are (ironically) falling into is to base the trapping sets
entirely around the trapping move-- this works sometimes, but moreover I think you just gotta treat Infestation like a tool to make the Pokemon succeed more, not the solely-riding crux of the set. (That right there is why most of the Whirlpool/Sand Tomb sets fail.)
