Each event is different. Super Vegito is weak against the Fierce Battle link, Merged Zamasu is weak against the Royal Lineage link and likes to super attack a lot, Buuhan is very strong and changes his type as he becomes weaker, Omega Shenron uses Coercion and is weak against GT characters, etc. Of course, they all are different types, too.

You have some very good cards (Super Vegito is an AGL leader, Merged Zamasu and Rosé are Extreme leaders, Buuhan is an INT leader, LSSJ Broly and Goku Black are PHY leaders, Omega Shenron is a STR leader...), but if you want to beat dokkan events you need to get to know your cards (their links, their passives, their special skills...) and adjust your strategy according to each event. You can find plenty of info on this Wikia, there's even a Tactics page about each event. You can also find plenty of guides on Youtube, if you want to see what a particular event is like, and how dokkan youtubers build their strategies. Of course, I'd also be willing to give you some tips if you have a particular event in mind, if that's the case feel free to let me know!
