I'm wondering when 3 minutes ago I could still use Machoke?The banning of Machoke basically buffed the entire meta. Because Machoke was so bulky and could check an incredibly large portion of the meta, anything that couldn't OHKO it before such as Electabuzz, the monkeys, Gabite, Fraxure, Rapidash, etc all got a little bit better. Rock- and Normal-types in general gained a lot of viability; especially the former because most Rock-types basically gave Machoke a free switch-in. And even with the banning of Machoke, lots of Pokemon that were hailed for the ability to reliably check Machoke are still pretty good because now they are less pressured and can opt to run other sets; Murkrow for example can now afford to forgo the Life Orb in exchange for Eviolite and play the bulkier role. Swanna on the other hand lost a decent amount of viability because not only was it a solid check to Machoke, but it was also a menace for Sticky Web teams because it had a good matchup against Leavanny was well as Pokemon commonly found on Webs such as Rampardos and Gogoat. Now that Sticky Web is banned, there's less of a reason to use Swanna as a defogger, although it's still the only good offensive hazard remover so it's not THAT bad.
The banning of Sticky Web hurt a lot of Pokemon as well as made others a lot better. Fraxure and Kingler depend a lot more on their Speed boosting moves in order to sweep through teams, and now they're a lot easier to revenge kill because of it. Other Pokemon such as Rapidash, the monkeys, Persian, and Electabuzz which depend a lot on their Speed, now have nothing to worry about and can now proceed to check many Pokemon more reliably. And then there's Pokemon such as Wigglytuff and Meowstic-F which were primarily used for their ability to punish Sticky Web teams, but now are more niche to punishing Defog. The former is still cool because it gets Stealth Rock and checks some pretty cool things, but the latter is really frail and weak as well as complete Scarf Krok bait, and not really worth it over other Psychic-types.
