Haste Pace - 1st Deck

i just started playing magic a few days ago, but this is what im aiming for as my first deck. im not made of money, so i avoided planeswalkers (lol rush deck), op roros beckoner, vexing devils, and probably going to tone down on the blood crypts (so expensive!). i started out with a return to ravnica - rakdos event deck (+ gatecrash fat pack + builders toolkit) so im sort of building off of it. tips and criticism are more than welcome! edit: replaced exava with hellrider since i dont run enough unleashed cards that lack haste. pulled some weapon surge cards in a couple packs and realized its utility and power make it a lot better than armed (also lack forests to fuse dangerous).
