How to make my magic deck better?

i don't have much to say other than that you have a lot of single cards in the deck if you can eliminate the cards that are not major or get more major cards that will help put you in a winning position. too many single cards lowers chance that you will draw the cards you need in order to win but if you have multiple of the same cards (4 being max) your odds of drawing them increase. hope i helped a little iv been playing for several years now. you will need more cards.. with red there are several approaches direct damage with instants and sorcery and few creature cards. there is the speed approach where you play small creatures with haste.. etc those are a few red decks are often related to direct damage.
