Keep floating in and out of the game?

Hello,

So I keep floating in and out of the game and am not sure what or where to start with deck building what’s good and viable options there’s just been so much growth with relevant cards and new support and so many more things. What I would simply like to know is what cards are staples and what are some good board breakers maybe ?

And if possible any niche techs some of you have.

Has everything just turned into make big board turn 1 and don’t brick ? It just all seems like you must have that ash or whatever just to play so you’re on level footing.
