hi... can u guys help improve my deck by adding T1 Cards?? my school friends (about 50 of them) usually play casually. They don't really care if it's T2, T1 etc etc... i was hoping to gain an edge over them by including some T1 cards into my deck.. ( i have cash, but i can't afford Powered Cards..

)

i know this deck is not T1 competitive.. but is it okay???
how can i improve it?? my budget isn't that big. My deck relies on getting my scepters+instants out, to lock the whole game down til i can get a win condition. =)
THANKS!! have heard alot about u guys' deck skills..
