Clefable @ Life Orb
Ability: Magic Guard
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk
- Calm Mind
- Moonblast
- Stored Power
- Soft-Boiled

clef def beats sab and stored power threatens stall, which sab is often on. evs are probably unoptimized.

Klinklang @ Leftovers
Ability: Clear Body
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Shift Gear
- Gear Grind
- Return
- Substitute

Infernape @ Choice Scarf
Ability: Blaze
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Flare Blitz
- Close Combat
- Earthquake
- Stone Edge

Calling Infernape out as a Counter.

As Infernape switches in, Honedge uses Swords Dance.

Infernape then uses Flare Blitz, which does a maximum of 90.4% to Eviolite Honedge. Honedge responds with +2 Sacred Sword that does 69.6% minumum.

Honedge can then get the KO with priority +2 Shadow Sneak, which does 46.4% to Infernape (69.6 + 46. 4 = 116%).

So, countering Honedge (though I guess this counters Infernape too)

Hippowdon @ Leftovers
Ability: Sand Stream
EVs: 252 HP / 144 Def / 112 SpD
Impish Nature
- Earthquake
- Stealth Rock
- Slack Off
- Stone Edge

Hippowdown can 3HKO and recover any health lost. Honedge can barely muster a 5HKO against Hippowdown (same with Doublade who I think was the original intention of Aaron).

Changing to include a Doublade just in case...

Swampert @ Leftovers
Ability: Torrent
EVs: 240 HP / 252 Def / 16 SpD
Relaxed Nature
- Stealth Rock
- Earth Power
- Scald
- Roar

Swampert 2HKO's with Earth Power. Doublade/Honedge can only 3HKO at +2 (not possible if Swampert switches in and EP's twice).

Swampert also beats Infernape. It 2HKO's and while Infernape can 3HKO, it can only do so with Close Combat, leading to defence drops that then change Swampert's attacks into a OHKO.

Budew @ Eviolite
Ability: Natural Cure
EVs: 36 HP / 236 Def / 36 SpA / 196 SpD
Bold Nature
-Synthesis
-Sludge Bomb
-Giga Drain
-Hidden Power Ground

0 SpA Swampert Earth Power vs. 36 HP / 196 SpD Eviolite Budew: 60-72 (26 - 31.3%) -- guaranteed 4HKO
36 SpA Budew Giga Drain vs. 240 HP / 16 SpD Swampert: 216-256 (53.8 - 63.8%) -- guaranteed 2HKO after Leftovers recovery
