What may seem like a weird partner for Abomasnow really isn't.
Rotom-Frost can come in (after setting up Veil) on the best Stealth Rock-setter, that Abomasnow will face a lot in the early rounds of the match; Sandaconda. Rotom-Frost also really really appreciates the 100% Blizzards from Abomasnow's hail, 'cause the 70% really feels more like 50%.
Another great synergy is the fact that Rotom-Frost and Abomasnow have similar switchins, due to their typing, which means that Rotom-Frost has a good shoot at breaking them 'cause they are most likely already weakened. Rotom-Frost in itself is decently bulky so it doesn't struggle that much setting up Nasty Plots but with Veil-support from Abomasnow it get's a lot easier.
Side note: on non Veil sets like Specs, Rotom-Frost can provide Defog for Abomasnow and also serves as a great pivot.
