Try add a third kaibaman, scrap the totem dragon (since you have warriors in the deck), and possibly scrap that soul exchange since it doesnt seem too useful. Also scrap cup of ace, you already have the summoner as a search card, and if you need more search cards try crystal seer.
I don't see the need of double summon, supremacy berry I'm 50/50 about, and definitely add 1/2 security orbs.
use the new card vanguard and get rid of one blue eye because you already have summoner to search for it. but honestly you might as well play last gamble with this deck
Make a new deck if you dont have vigilance.. you go all the trouble of summoning a bewd, which is your core card in your deck, only to be countered by your opponents order of charge, econ, relinquished etc.. a broken deck if you dont have vigilance
