SIDEBOARD
i only have these two for certain counters, open for suggestions
Vampire Hexmage to stop creatures that grow from counters or artifacts that stack
Spiteful Shadows renders walls and high defense/low power creatures useless cuz the damage just goes through

The object of this deck is to utilize direct damage to get the trigger bloodthirst. It was inspired by the Life Steal mechanic in League of Legends. Basically, whenever damage is dealt, life should be recoved in some way by the card directly,(Taste of Blood), by lifelink(Vampire Outcasts) or by creatures getting bigger through bloodthirst.(Bloodlord of Vaasgoth)
Example combos:
turn 1 - Swamp - Pulse Tracker
turn 2 - Swamp - Attack with Pulse Tracker. Even if they block, it does 1 damage for Duskhunter Bat to come out as a 2/2


Vampire's Bite helps get extra damage out if they can't block flyers. Bloodlord of Vaasgoth comes out as a 6/6 flyer for 5 mana with Piranha Marsh
Geth's Verdict takes out a creature and triggers bloodthirst and Feast of Blood can take out any color creature for only 2 mana.
