Forum:SpellCaster Beatdown back fires

Right now I have an spellcaster deck that I did basically buy all individually, the form of which I built the deck it's focused on stopping my opponent from doing anything to stop me or screw me over. I also have some spells that would advise I would just try to win in just two or three moves when everything I need is set, (Which doesn't happen every often), but in certain duals my deck does have the attendancey to backfire on me and make me ultimately lose by my own cards. Do you people have any suggestions that could help me make this deck less brute to me and more to my opponent? It's good at some points and others it just makes matters worse for me.

If you could tell me which might be good or bad to have for this Spellcaster Deck, or what I could even add that would be very helpful; Thank you.
