+ research

go look at decks on other forums. Just having "all spellcasters" doesn't mean your deck has a strategy. Without a focused strategy, you won't win against even halfway decent decks. Cut your deck down to 40 cards so you can draw your more powerful cards more quickly. Add in draw engines. Get rid of cards that lose you card advantage (like Magical Mallet) without giving you any actual field advantage. In general, do your homework before posting a deck. This deck is unfixable.
