Some personal thoughts on this challenge: Whilst the core might synergize well on paper, stall starts becoming a real problem once you factor in the fact that they have two direct counters that they can't cumulatively break and/or pressure enough: Magearna and Necrozma-Dusk-Mane, the two most dominant Steel-types in the tier completely invalidate this core. I personally would prefer to pair Naganadel with Keldeo, as whilst Naganadel does appreciate having the Psyterrain support, there are difficulties with utilizing it due to its low duration. Keldeo, however, appreciates Magearna and Duskmane being worn down - it happens to have little to no counters either, and removing one of them from doing so is an absolute joy for it.
With Gen 2 VC now being a thing, I wanted to take advantage of my power to force you all to ladder with certain Pokemon and extend it to forcing you all to play with certain sets on certain Pokemon. I swear, they're not (too) bad.
