Forum:NEED HELP 2 QUESTIONS

i have a macro deck and i want to get it down 40 cards so i can draw the right cards but i'm worried that i would end up using all my cards before i can destroy my opponent. also i feel like its missing something. all my monsters are below level 4 but i do have 2 stardusts and 1 black rose dragon. what should i do

also (2nd question) i want to make another deck... either a lightsworn or a beast deck tell me which one you think is better along with booster packs or even structure decks i could buy with some tips and strategies

thanks
