Did you get the event Surskit in Peridot Ward? If so you can train it up until you get Sticky Web, evolve it, and then train it up some more and use it to get up the web and set some speed control. Your team is extremely slow so it would be useful.
You could also get a Stunfisk and trade it for Vulpix in Agate Circus and then use the stolen Cyndaquil from 7th street with the Sticky Webs. Drought + Typhlosion Eruption and a seed (synthetic I think?) will ensure a one shot on everything bar maybe Umbreon.
