coming back to vanguard?

so i’ve been awhile from vanguard for awhile now.. last i played was with bavsargra… i also have V Vanquishers.. I heard about the new mechanics and was wondering if i should come back to the game… i originally stopped cuz i didn’t have anyone to play with and locals weren’t fun anymore. should i get the new decks or is bavsargra still valid to play?
