The full list of Deltas able to learn Baton Pass is:
- Delta Maractus
- Delta Emolga
- Delta Scyther/Scizor
- Delta Froslass
- Delta Plusle
- Delta Minun
- Delta Gorebyss
- Delta Huntail
- Delta Drifblim
- Delta Dodrio
- Delta Blaziken
- Delta Girafarig
- Delta Ambipom
- Delta Mawile
- Delta Medicham
- Delta Lopunny
The potential mega evos are:
- D. Lopunny
- D. Medicham
- D. Froslass
- D. Mawile
- D. Girafarig
- D. Scizor
Right off the bat, the least useful mega is probably D. Scizor. Adaptability doesn’t contribute anything to the team. Intimidate from Delta Girafarig helps set vs more physically offensive mons, Magic Guard on D. Froslass completely walls Chansey, D. Mawile can trap certain mons in, etc. D. Mawile lost all its infamous attack boosts however. In addition, there are no speed boost users, so this doesn’t help D. Scizor. You probably won’t run any of the Scizor line as it’s too frail or too slow.
So I would run D. Maractus right off the bat due to it’s access to Shift Gear, one of the best boosting moves in the game. Essentially Dragon Dance but with an extra speed boost. This thing is a special attacker, which is sad, cuz it has some neat priority in Bullet Punch and Mach Punch. Sadly, even on Baton Pass, 86 Base Attack won’t cut it most of the time. I’ll put 2 sets, the other nice thing about this mon is its great coverage in Overheat, Thunderbolt/Discharge, and Energy Ball. It also has nice physical options in the aforementioned priority and Knock Off, Meteor Mash, Thunder/Ice Punch, Zen Headbutt, and Pursuit. Some problems are its defenses of base 67 and base speed of 60.

Next thing I noticed is that Delta Dodrio isn’t going to be very helpful for this team, anything it can do, D. Blaziken can do better, the main advantage it has is Hypnosis, which is rather unreliable. Even Future Sight, which can help force your opponent into certain plays, D. Blaziken does better. D. Ambipom doesn’t have great boosting moves, so nope to that. Again, similar problem with D. Drifblim, outclassed by D. Emolga and D. Plusle in almost every way. Stockpile seems appealing as you can pass and it will keep the defense boosts but not the Stockpile counters, but then you realize it has the defenses of a Snom. The main advantage to the clone twins is Quiver Dance, and for Flying Pikachu, it’s Nasty Plot and Will-O-Wisp. That, and the totally not broken Blaze Boost. Imagine this thing with some defense boosts…
About that, Defenses are the next requirement. Delta Blaziken can run a potent special set with Baton Pass, Future Sight, Air Slash, and Cosmic Power, or a more classic set with SD, Brave Bird and Roost spam. The Clamperl evos get Coil and Shell Smash, so that’s another offensive boost. The main problem here is lack of defense, and all the pokemon are frail. This makes me think that trapping with D. Mawile or Intimidate with D. Girafarig may be useful. D. Girafarig has access to Iron Defense and Intimidate. D. Mawile has a higher base defense, but both have a subpar defense of 95. D. Girafarig has a better typing, but Mawile has Ingrain and Taunt, with STAB Knock Off, SD and CM. I would think D. Mawile is probably more useful.
