In this budget verision I don't use blazing cartesia but I think it is preferable then the magistus package. You could also consider playing 3x branded opening and an aluber so that If your normal gets blocked you can extend and fusion summon.
Pro tip, you are going to banish a lot when you need resources, use lubellion and patronus (you can search it with fabretta and take it from the gy with vice-madame) to put them back in the deck.
You can also add a shaddoll beast or a dark magician to make winda and dragoon respectively with branded fusion.
In the most recent builds I am considering timaus over the second holiday.
Have fun
