While this deck is on a great budget currently, do not be mistaken, I designed this deck with the sole intention to compete with a majority of top decks in this format, and I believe I have succeeded.
Demon of Catastrophes is the all star here in most match-ups; with Rite of Belzenlok, Ravenous Chupacabra, and even Fungal Infection in the mainboard for some easy fodder to sack. Isareth the Awakener + Ravenous Chupacabra
loops are also available, as well as a healthy amount of other creature* removal cards for this explosive midrange deck.
Kind of divvying up the removal before post-rotation meta becomes pronounced. Divest supports the curve, and is the best solution for Vine Mare, whom you could imagine is a nuisance against this deck. Cast Down and Walk the Plank are both necessary too. Dire Fleet Poisoner also may act as a psuedo-removal spell if used in such a manner. The poisoner may seem out of place, but that's exactly why it works (although a lot of common 3-mana threats are, in one way or another, not particularly threatened by "the poison").
Phyrexian Scriptures is devastating in certain match-ups. Initially I was worried that the 1 turn "warning" the board is about to be swept will be a downside compared to a more traditional board wipe, but often times opponents spend a turn not casting creatures they would have, because they're going to get wiped out when my turn rolls around (as well as beaten down by Dread Shade or whatever immediately after).
Forebear's Blade you may notice in the sideboard. Not a lot of folks are running it, because it's slow, but between the synergy with Dread Shade, tokens, and granting creatures the ability to avoid at least half of white's removal spells, I believe sneaking 1 in the sideboard is a good call.
