You are actually much closer to this than it looks - can trade for two BSM from excess fetches, could use another blood crypt until you get Blackcleave cliffs.  Blood moon is expensive, as is collective brutality.  But both are sideboard cards well worth having.


4 Bloodstained Mire - Base BR deck
3 Scalding Tarn - Any Red Fetch works
3 Mountain - Not a DS deck + extra path insurance
1 Swamp - Blood Moon Insurance
2 Blackcleave Cliffs - Contemplating going to 1, Not a DS deck
3 Blood Crypt - Ran into issues running out of fetchable shocks with 2
1 Stomping Ground - Ancient Grudge Flashback
4 Hollow One - Core
3 Gurmag Angler - Core. Down to 3 since hands with 2 or more gurmags are suboptimal
4 Flamewake Phoenix - Core. THIS is the vengevine style payoff of the deck. Incredible synergy with the Gurmag/Flameblade/Hollow one plan while also serving as a 3 mana hammer of bogardan style topdeck burnspell in mid/late game.
4 Flameblade Adept - Core, absolutely best turn 1 play in the deck, unless you can power out 2 or more hollow ones
4 Bloodghast - Much easier to trigger than vengevine
4 Faithless Looting - Core
4 Street Wraith - Core
4 Burning Inquiry - Core engine. You will get varianced from time to time, but the draw/discard power of this card is exactly what you are looking for with the added bonus of sometimes manascrewing your opponent
4 Goblin Lore - Similar to Inquiry. Reason this gets the nod over Reunion is that a single draw 4/disc 3 allows for hollow one shenigans while also enabling a flameblade to start bringing back flamewake phoenix and not running into the awkward worst topdeck ever issue.
4 Lightning Bolt - Good reach + interaction. Better than push since we ARE an aggro deck
2 Fiery Temper - Good synergy with looting effects while also giving additional reach lategame. Best way to think of this card is flamewake phoenix 5-6 rather than bolt 5-6
2 Edge of Autumn - Worst card in the deck, but important since it (1) gives 5-6 redundancy of the street wraith effect & (2) gives the extra push to enable flameblades to reliably return flamewake phoenix. Edge of Autumn is to BR Hollow One what Memnite is to Affinity.
Sideboard

2 Blood Moon - Good against big mana as well as UW/x colonade decks. Turn 1-2 Beater into Turn 3 blood moon is very effective at closing out games
2 Big Game Hunter - Deck has an issue with X/5 toughness creatures G1 like Goyf/Gurmag/Tasigur/Shadow, so BGH provides a nice synergistic solution.
2 Ancient Grudge - Affinity and Lantern are 2 of the decks worst mus, so very important. Strong synergy with random looting.
2 Grim Lavamancer - Absolutely incredible vs DnT/Coco/Tribal decks. So good I'm considering making room in the MD.
4 Leyline of the Void - Anti-Dredge/GDS/Storm yard plan. Considering going down to 3 nihils or faerie macabre to open up sideboard space.
1 Lightning Axe - Similar role to BGH
2 Collective Brutality - Anti-Burn/Combo
