OBJECTIVE
With this deck, your main objective will be to make your opponent loose lives while you gain a lot of lives. Due to its easy mana curve, it would be odd if you can't play something every turn.
In order to make your opponent loose lives, you will give him token creatures, and he will loose lives either when the creature enter his/her battleground and when it dies.
USAGE
Main Use
Try to have at the same time Forbidden Orchard and Illness in the Ranks. THAT will give your opponent creatures that enter the battleground and then automatically die. Play Hunted Troll to increase number of creatures given to your opponent.
This alone, just grants you with 1 mana of wichever color you want. The magic happens when you play Blood Artist and/or Blood Seeker.
As the game goes by, try to play Sangromancer, as that will buff your live management rate.
Secondary Use
Massacre Wurm will be a great game-ender if your enemy has lots of creatures, Deadly Recluse will keep those pesky flying creatures away, and Bottle Gnomes
+
Glissa, the Traitor
will grant you a permanent live income.
Also, this deck have a great creature control as well as some buffs like Ring of Xathrid, Deathrender or Eternal Thirst.
STRENGS
HUGE live loose to your opponent if you manage to have Blood Artist
+
Massacre Wurm
+
Sangromancer
. Eternal Thirst plus any creature with deathtouch will make a great combo as well.
WEAKNESESSS
IDEAL STARTING HAND
Forbidden Orchard + Illness in the Ranks + Blood Artist + Swamp + Geth's Verdict + Abrupt Decay + Hunted Troll
Note: If you don't get a Forbidden Orchard on the opening hand, try at least to have 1 Forest in it. There are few of those and you will need them. Otherwise, ... Mulligan.
