Forum:My Alien Deck

My alien deck is really good and it works well and stuff,but it sucked in a way during a tournament.I changed it around a little after the tournament and it still needs a few tweaks,so i just want to know if i can make it stronger at all.I also wanna know if my deck can even wreck blackwings or lightsworns and maybe even stronger decks.I wanna know if i just got bad hands or something,and it is actully a great deck.Well without further disscusion, this is my alien deck.
