Need help making a Deck for the Gogeta promo leader.

So awhile back, I signed up for the Broly promo release and got the two exclusive leader cards Broly and Gogeta. I gave my friend the Broly card because it's his favorite character and I held onto the Gogeta. We thought it would be cool to make decks for them so they could duke it out card style but although we know how to build his, I have no clue what to do with mine. I saw on the channel they used one but they don't have a video for how to make it but it looked cool. It had the goku/vegeta cards, veku's and stuff that made it seem like a fun deck to play that could also compete. He said it had a lot of expensive cards so I don't expext to be able to build it right away but if someone could tell me or point me where to get a good playable start on the build, I would be very grateful and appreciative. I understand there are expensive cards out there that I'm willing to get eventually but as long as I can get help with putting something together that's decent and playable then I can have something to work with while I save up for those juicy upgrades later on.
