I regularly have trouble cutting out the last 30 cards from my brews, compared to the last five or six cards with other strategies

Take a look at the entire Commander deck below: Creatures (36) 1 Vampiric Dragon 1 Malakir Bloodwitch 1 Vampire Nighthawk 1 Anowon, the Ruin Sage 1 Butcher of Malakir 1 Nirkana Revenant 1 Bloodlord of Vaasgoth 1 Rakish Heir 1 Falkenrath Noble 1 Stromkirk Captain 1 Blood Artist 1 Dark Impostor 1 Necropolis Regent 1 Falkenrath Gorger 1 Indulgent Aristocrat 1 Stromkirk Condemned 1 Stromkirk Occultist 1 Bloodline Necromancer 1 Bloodsworn Steward 1 Crimson Honor Guard 1 Patron of the Vein 1 Sanctum Seeker 1 Champion of Dusk 1 Bloodtracker 1 Cordial Vampire 1 Anje's Ravager 1 Strefan, Maurer Progenitor 1 Bloodtithe Harvester 1 Timothar, Baron of Bats 1 Crossway Troublemakers 1 Scion of Opulence 1 Kamber, the Plunderer 1 Midnight Arsonist 1 Markov Enforcer 1 Shadowgrange Archfiend 1 Laurine, the Diversion Lands (37) Spells (27) 1 Sol Ring 1 Ancient Craving 1 Night's Whisper 1 Fire Diamond 1 Charcoal Diamond 1 Rakdos Signet 1 Urge to Feed 1 Swiftfoot Boots 1 Blasphemous Act 1 Underworld Connections 1 Rakdos Charm 1 Vandalblast 1 Unstable Obelisk 1 Commander's Sphere 1 Mob Rule 1 Damnable Pact 1 Avacyn's Judgment 1 Stensia Masquerade 1 Arcane Signet 1 Molten Echoes 1 Feed the Swarm 1 Sinister Waltz 1 Glass-Cast Heart 1 Olivia's Wrath 1 Predators' Hour 1 Arterial Alchemy 1 Imposing Grandeur What do you think of the Vampiric Bloodline deck and Timothar, Baron of Bats

I am always looking for an opportunity to get creatures into the action, especially in sideboarded games
Any legendary creature can be your commander, but every card in your deck must share a color with that creature
Discard fares a little better, but only if you can play so much of it that it does start to leave the opponent without good plays on their turn
