Something fun to do with Prankster:
Conkeldurr @ Leftovers
Ability: Prankster
EVs: 216 HP / 252 Atk / 40 SpD
Adamant Nature
- Substitute
- Focus Punch
- Knock Off
- Drain Punch
Thanks to Riolu, all pure Fighting-types get access to Prankster. What came to my mind was using Conkeldurr as an abuser of the SubPunch combo. It abuses the combination very well with 101 HP Substitutes (which is what the EVs are for) and its unrivaled-by-any-non-Mega-Fighting-type Attack stat. Knock Off is for coverage and utility; Drain Punch is somewhat filler but potentially allows Conk to gain back HP for more Substitutes.
Other abusers of Prankster SubPunch:
Much faster but weaker and more frail; packs U-turn but no other notable options (not to mention no Knock Off)
Faster and slightly bulkier on the special side, but does not get Drain Punch (for some reason)
Faster and with nice special bulk, but very frail on the physical side and lacks Drain Punch
Slightly bulkier but slower and weaker Hitmonlee, except it has Drain Punch but no Knock Off
Higher HP stat but weaker and with poor all-around bulk (and no Drain Punch)
Good all-around bulk and Pain Split, but it's weaker
Faster but slightly weaker and more frail; also gets Pain Split
The fastest abuser who can also use U-turn or Baton Pass
(Note: Conkeldurr, Hariyama, and Throh are the only ones on the list with 101 HP Substitutes. Gurdurr as well, but Gurdurr < Conkeldurr.)
The unfortunate thing about this strategy in general is that it gets destroyed by birdspam and Pixilate Hyper Voice, not to mention there is no pure Fighting-type with reliable recovery (the closest match being Throh and Sawk with Pain Split), but I thought I would share it anyway.
