Verdurous Gearhulk:
Verdurous Gearhulk is here for three reasons:
1. Should you not draw heartless summoning it is good on it's own.
2. If you do draw heartless summoning it is a 3 mana 7/7 trample. (Really scary)
3. once you have heartless summoning out you can cast it for 3 maybe get in a hit maybe not. It will get removed. Then, since it is an artifact you can return it with a
Myr Retriever.
Verdurous Gearhulk +
Heartless Summoning is a very aggressive combo that can win you the game against control or save your life against aggro.
Grim Haruspex: Grim Haruspex is essential to this deck. Virtually all of the creatures in this deck combo in most satisfying ways with this card. Aside from Heartless Summoning the cards in this deck have been picked to have the best possible effect with Grim Haruspex. the most notable of combo's with Grim Haruspex is the Grim Haruspex + Mulldrifter + Heartless Summoning. Mulldrifter + Heartless Summoningis already insanely good. it's either a 1 mana draw 2 cards or a 3 mana draw 2 cards and get a 1/1 flying although you will almost always use it as a 1 mana draw 2. If you have Grim Haruspex which is already a 1 mana 2/1 with Heartless Summoning you can turn Mulldrifter into Ancestral Recall. another combo to use with Grim Haruspex is: Grim Haruspex + Heartless Summoning + Ruthless Ripper + Obscuring AEther. This combo is effectively a 0 mana deal 2 damage draw a card. Yet another combo with Grim Haruspex is with Myr Retriever. if you get a Heartless Summoning, 2 Myr Retrievers and a Grim Haruspex you literally draw your entire deck and use Falkenrath Noble to win.
Mulldrifter: This card is one of our best combo's with Heartless Summoning. it functions as a 1 mana draw 2. It also triggers creature dying effects because it is sacrificed.Mulldrifter is great in combination with Grim Haruspex and Falkenrath Noble. Mulldrifter is one of the main reasons this deck is able to be successful.
Myr Superion: this card is the most common Heartless Summoning combo. it is a 0 mana 4/5! Myr Superion is both a win condition and protection against aggro because it is hard to kill you can play it early and it can be returned to play with Myr Retriever.
Den Protector: Den Protector has some very interesting uses in this deck and is one of the reasons I chose to put morph in this deck instead of just lots of evoke. this deck uses Den Protector better than any other deck I know. you can play it as a 0 mana 1/1 on turn 2 using Obscuring AEther and Heartless Summoning. once it is in play you can use it basically as a better Regrowth/Eternal Witness. this is vital to the deck because it allows you to bring back anything from a Mulldrifter to a Slithermuse to a Verdurous Gearhulk. In addition if you don't start with Heartless Summoning you can cast it as a low mana creature to keep you alive.
Falkenrath Noble: this card is important because it is usually how we win. the good old Myr Retriever + Myr Retriever + Falkenrath Noble + Heartless Summoning combo will win you the game because you can constantly play a Myr Retriever, return a Myr Retriever to your hand, play it and so on. whenever a creature dies your opponent takes one damage so you deal damage to them and you gain life.
Myr Retriever: this card is just part of a fun little combo I thought of. you play Heartless Summoning and suddenly Myr Retriever is 0 mana return an artifact from your graveyard to your hand and also triggers creature dying effects. play a second one and you have an infinite loop of creatures entering the battlefield and then dying. this is where Falkenrath Noble kicks in. you can use this combo to win on turn three so that's pretty good. I could have added Altar of the Brood and made it possible to win on turn two instead but I like Falkenrath Noble because it is useful on it's own and if you have Grim Haruspex in play you can't win with unless you have Laboratory Maniac in play. I am still play testing so the list might change and I mist add Altar of the Brood but right now i'd rather have consistency than the tiny possibility of winning on turn 2.
Slithermuse: Slithermuse is the reason I added so many morphs and Obscuring AEther. on turn 2 if you played an Obscuring AEther and a Heartless Summoning you can cast all of your morph cards as 0 mana 1/1's. now that is pretty nice on turn two but wait for this next part. Your opponent likely has most of their cards in their hand and if you had only morphs and a Slithermuse in your hand you can cast Slithermuse evoked and refill your hand for 2 mana leaving you far ahead of your opponent with a better hand and a better board state on turn 2. This also lets you search for more combo pieces and there might be a Myr Superion in that new hand.
whenever playing against aggro I suggest replacing Slithermuse with Fog or Dragon's Eye Savants.
Ruthless Ripper:Finally, Ruthless Ripper is great if you get all of your combo pieces. With Heartless Summoning, Grim Haruspex, and Obscuring AEther it is a zero mana draw a card, deal 2 damage to target opponent. just replace it with a new card and hit your opponent for a few points. However, the main reason Ruthless Ripper is in here is if you don't have heartless summoning then it is just a 1 mana 1/1 with death touch. it can keep you alive until you get that combo!
