Now this list is thrown together from cards I already had and a small online order of edh staples. For this deck I am looking for ways to improve its overall performance mainly ways to do big and fun potentially Johnny things without getting to broken. I would also like help just assessing the decks overall capability.

With some constraints being:
- not too broken as my lgs is not wanting to get overly broken eg not too many time effects, 2 card infinite combos etc.
-keeping budget in mind. Yes there are expensive cards in this deck but I don't have the money right now to drop big bucks on edh just yet.
