[MtG] Budget Standard UB Aggro Combo

[Mysty]

So far, I just have a basic idea of all the stuff I want the deck to do, and I'll draw up a decklist at the end. Here's my idea:
• Use early-game Vampires to put pressure of the opponent and make the opponent use their kill spells.
• If the opponent doesn't kill my Vampires, Bloodline Keeper is going to have a party as Lord of Lineage.
• Civilized Scholar serves dual purpose of looting out my combo as well as being a 5/1 beater a good amount of the time.
• Grimgrin serves as a late-game beater, allowing me to sacrifice Bloodline Keeper's vampires and blow up opponent's Titans.
• Necrotic Ooze then abuses a Lord of Lineage, Grim-Grin, and Trespassing Souleater in the Graveyard to boost itself to infinite power and toughness and swing for unblockable.
• Swiftfoot Boots helps keep my Grimgrins, Bloodline Keepers, and Necrotic Oozes safe and able to attack quicker.

Now to get to what I had in mind. I'm not entirely sure on the numbers, but this should work out as a guide:

12x Vampires (likely 4x Blood Seeker, 4x Vampire Interloper, and 4x Child of Night)
4 Civilized Scholar/Homicidal Brute
2 Trespassing Souleater
4 Bloodline Keeper/Lord of Lineage
2 Necrotic Ooze
3 Grimgrin, Corpse-Born
3 Swiftfoot Boots
3x Mana Leak
3x Dismember
24 lands (probably something like 16 swamps and 8 islands. I don't have any duals and I probably won't get them unless they're really cheap)

Please fix this up. It looks like a hilarious deck that I'll test for fun when I can build it, but even so, it could use fixes to make it better and/or cheaper.
