>>41967164I MMed my own HA Shiny Quagsire and the only concern would be getting HA on the shiny. Some people get very unlucky and have 3-4 non HA shinies before getting their HA shiny. If you're willing to risk it go for it. I haven't gone on Ranked yet (still tweaking the team) but Quagsire's one of the MVPs on my online Doubles Team.
And Wooper's fucking adorable.
