The idea of this deck is to give your opponent creatures and to make them pay for that gift in huge amounts of life loss.
Blood Artist - combos well and makes your opponent think twice about attacking you with the 1/1's you give them. Your 3 Timely reinforcements becomes a 12 point life advantage when traded with 3 goblins, spirits or elves. Play a Massacre wurm with this guy out and it's likely game over.
Suture priest - is a real engine here. playing a hunted phantasm with one out to do 5 loss of life or tapping an exotic orchard to cause 1 loss of life gives the deck real reach.
Mercy killing - Targeting a threat with Suture priest out also becomes brutal allowing you to deal loss of life equal to the sacrificed creatures power or you could potentially sack a Massacre Wurm or phantasm to gain life and numbers with Suture Priest out. Give em an arm then play Massacre Wurm.
Massacre Wurm - Straight forward guy here he gets rid of the spawns you create and hits your opponent for 2 loss of life for each 1. So if you've played a phantasm Massacre Wurm deals 10 damage on entry.
Restoration Angel - flash speed flying and momentary blink. Yes Please.
Venser, The Sojouner - Versatility; Extra mana from a tapped land. Blink creatures for battlefield effects. Or even help a Massacre Wurm get through. Also playing Massacre Wurm and then exileing him again on the same turn for a -4/-4 practically a board sweeper.
Solemn Simalacrum - land draw, replaces itself and combos nicely with Venser to draw land and turn the late draws to your favor.
Timely Reinforcements - Good utility, helps you gain a lot of life with a Souls Attendant and Suture Priests out. With City of Brass and Forbidden Orchard your almost always down on health and creatures early. this lets you keep the odds closer.
I've thought a lot about the possible interactions but not sure about the exact way I want the deck to be built. I would like tips on main deck and sideboard please.
