A deck that utilizes spells like Act of Treason and Mark of Mutiny to steal opponents creatures, swing with them, and then sacrifice them for beneficial effects. I don't actually own this deck, so it is all just based off of what I brewed up in my head. If you have any suggestions don't forget to comment and +1
Sacrifice Ability Cards
Demonlord of Ashmouth: A 5/4 with Flying for four mana that combos with our sacrifice theme? Whats not to love. Sometimes it's too mana intensive to stack Demonlord on top of our steal spells, in these cases he combos well with Strangleroot Geist and Sprouting Thrinax. Drop a Sprouting Thrinax T3 and then on T4 drop your Demonlord of Ashmouth and have your self a 5/4 flying creature and 3 more pawns for sac'ing on T5 when you bring out your Mycoloth (ideally).
Bloodthrone Vampire: A low mana creature that gives us an easy sacrifice mechanic to use. Combining her with Sprouting Thrinax can pump her up to a 9/9 for 3 mana. Can surprise your opponents if timed right.
Tymaret, the Murder King: Another low cost creature that gives us multiple sacrifice abilities. Lets us burn our opponent directly while sac'ing their creatures. Adding injury to injury. His second ability makes him another option for sacrifices. Kill him to bring out your Demonlord turn 4 then on turn 5 steal an opponents creature and and sac it to bring Tymaret back to your hand.
Scarland Thrinax
: A solid creature that gains permanent +1/+1 counters from sacrificing creatures. My favorite sac creature because you can gain lasting field advantage via his permanent counters while Bloodthrone only gets a temporary boost.
Creature Steal Cards
Mark of Mutiny: The bread and butter of this deck. Lets us steal a creature to sacrifice, but lets us pump it up while giving us the option to swing with it before we sac it. Most effective with
Scarland Thrinax
and Bloodthrone Vampire, as their abilities cost no additional mana.
Act of Treason: Another creature steal spell, not as good as mark of mutiny, but a solid choice for the deck.
Grab the Reins: Much like the two spells above, however, Grab the reins gives us the choice of stealing an opponents creature or sac'ing a creature and dealing its power as direct damage, or doing BOTH. Bloodthrone Vampire+Sprouting Thrinax+Grab the Reins can give you 9 direct damage to target player or creature. Risky but could possibly win the game.
Sarkhan Vol: A very useful spell for the deck. Can be used to steal multiple creatures, or to pump up your creatures for some extra damage. His +1 Works well with Sprouting Thrinax's tokens
Everything Else
Mycoloth: A heavy hitter that plays well into our theme. Can keep the fun going by giving us even more creatures to sac after devouring Sprouting Thrinax and some tokens.
Strangleroot Geist: A low CMC creature that gives us some more aggro and another creature to sac.
Sprouting Thrinax: One of the most vital cards to the deck. Works as an amazing sacrifice creature. Gives you 4 creatures to sac for 3 mana. Combo's with most cards in the deck. Use it, sac it, love it.
Well I think that about covers the deck and how it plays. As I stated above I haven't actually tested it at all so don't be afraid to make suggestions or tell me what you think works or what doesn't. Feel free to share your experiences with the deck. If you liked the deck don't forget to comment and +1!
