For secondary ability since magic guard is such a strong I'm going to throw out a suggestion that could seemingly be on par with those and that is Compoundeyes. Compoundeyes allows MonoCap1 to throw its stronger STABs such as Blizzard and Fire Blast with less fear of missing increasing the reliability of Scarf sets for MonoCap1 and making up for the loss in power w/o life orb. This even boosts Inferno's accuracy to a decent but still inaccurate 65% which means that Compoundeyes MonoCap1 could cripple switch-ins semi-reliably with one move which further helps scarf sets.

For a spread I think speeds that outrun all of dragon or steel without scarfs isn't the way to approach MonoCap1 as a pokemon needs checks and counters and even without them Cap1 will still be a boon against these matchups if played correctly. If a player wanted MonoCap1 to simply beat these archetypes without prediction it could simply throw a scarf on it and then you only have to play against e-speed banded D-Nite. Monocap1 at 122 or 115 speed also outruns a lot of pokemon from other types that it really shouldn't giving fire and ice a much bigger advantage against flying, psychic and fairy types that we are not targeting as the MUs that MonoCap1 is supposed to fix.
Now I'll talk about defense and why I chose to give MonoCap1 so much more defense than special defense this investment is made to deal with priority especially Mega Scizor a pokemon can pretty much destroy standard ice alone.
Giving it an almost guaranteed chance to be able to check defensive Mega Scizor at least once during a match and Scizor is a mon that pretty much auto wins if SR are up and it gets to +2 v Ice. While its is given a paltry 40 special defense so that it basically loses to any bulky special attacker on the other side as a consequence of giving it such decent defense. I believe that a MonoCap1 that is not able to deal with mega scizor in some aspects will fail that mission of giving Ice a small answer to steel. If Monocap1 is given access to will-o-wisp it will also help it fulfill a small purpose in most any match up by burning physically aggressive attackers and being able to survive with its great speed and alright defense therefore giving it a purpose so that it is not dead weight vs other archetypes.
For reference this is the set I'm envisioning as the standard for Monocap1:
MonoCap1 @ Life Orb
Ability: Magic Guard
EVs: 8 Def / 248 Spa / 252 Spe
Naive Nature
- Ice Beam
- Will-o-Wisp
- Ice Shard
- Flamethrower / Fire Blast
Despite giving MonoCap1 mixed offensives I can see very little reason to run it as a mixed attacker instead of as a special attacker with the spread I proposed since the only relevant boost a mons gets from Attack vs these archetypes is access to Ice Shard because Flare Blitz doesn't OHKO anything Fire Blast does not vs. Steel which means that the recoil and giving up a move slot are simply not worth it. Therefore I moved a bit off of attack and onto and onto special to give it an SpA of 120. While this Special Attack may seem like a bit of overkill for MonoCap1 it is important since it allows MonoCap1 to run non LO sets without missing the power too much provided it is running Fire Blast or even Blizzard
For reference this is the set w/o LO that I think will still see usage
