Help with deck building

So I want to build a new deck for Super Brainz because the one I have isnt working much. All my opponents have better decks built “with a purpose”, but my collection is not that big so I have more problems to build something like that.

I know theres a pinned post on this sub saying which things to do when asking for help, but for example I cant say how I want to play the deck cause I dont know where to start

Id appreciate if u guys can help me with which card i should use or which strat i should work into :)
