Kykar's Kooky Spells (EDH / Commander)

Intro
Thanks for taking the time to check out my deck! This is what I am looking to keep as one of my only two EDH decks, as I am currently downsizing my collection and involvement in magic. After playing a lot of cEDH, I want to make a deck that is more fun for me and table (As well as being as being relatively budget conscious.) This deck is made up of two types of cards: ones I love for their awesomeness like Thousand-Year Storm, Jeskai Ascendancy, and Melek, Izzet Paragon, and cards I love for their efficient effects. Mainly looking for any advice on streamlining the deck, particularly in the manabase.

Gameplan
Storm is the name of the game with this Kykar deck, attempting to utilize a slew of low CMC cantrips and copied rituals to kill the table with Expansion // Explosion, Ignite Memories, Niv-Mizzet, Parun, Conflagrate, or as a last resort getting in spirit beats helped by Jeskai Ascendancy.
Since I have come to EDH from first a Modern/Legacy and then cEDH background I always love having cheap and efficient interaction, especially since the time I get to play on my turn is reduced in a multiplayer format. Any suggestions on interactive cards that you have found particularly helpful or fun would be appreciated.

Budget
Since this deck is being created as I am selling my collection I already owned most of these cards, which give me an interesting perspective on budget. I am okay with keeping cards I could sell if it means this deck will run more smoothly or be fun to run. Still I recognize that these are still bits of cardboard with little worth outside of a strict game sense, it isn't the most financially healthy thing to have thousands of dollars invested in them. Plus budget decks will have a greater chance of being balanced against a wider array of possible decks. That is all a long winded way to say that I am always interested in suggestions that are budget conscious (Trying to keep the deck below $200.)

Politics
This needs its own section since I am hoping to make this a sub-theme of the deck. I personally love interacting with my opponents/friends and I know adding cards that increase player involvement will provide that interaction in a fun way. With that in mind I am looking for cards that get other players interacting on my turn and still fit the theme, cards that require voting like Split Decision or cards that uplift the table like Minds Aglow.
