This is my take on a control/midrange deck for SOI standard. I originally wanted to build this deck as soon as I saw Autumnal Gloom
. It might not be the best card, but I absolutely love the flavor, artwork and mechanics of it. I also love Treefolk, so I knew I wanted a full playset of those.
Aside from that I added several cards that help me achieve delirium, which is a small mechanic in the deck and other cards for control.
As far as creatures go, I added:
Sylvan Advocate because he is one of the best 2 drops in the game and gets better late game.
Soul Swallower for a creature that can get really big.
Obsessive Skinner for a great delirium effect of buffing my creatures and helping to take some out of range of spells such as Languish.
Nissa, Vastwood Seer
for a creature/planeswalker that plays really well with advocate, provides card/land advantage, and can put out a pretty nice creature.
Mindwrack Demon for a great flier that drives achieving delirium, is out of range of languish, and is all-around awesome.
I also added a good bit of control/creature destruction, which are as follows:
Dead Weight provides cheap control or kills my opponents creatures and drives delirium when the creature dies.
Ob Nixilis Reignited is an awesome walker that provides card advantage, creature control and great payoff if you can get to it.
Corpse Churn puts cards in my graveyard for delirium and pulls out a creature if needed.
Traverse the Ulvenwald provides land fetch and creature fetch with delirium at a great cmc.
Ultimate Price to help deal with troublesome mono creatures.
Languish for one of the best board clears in the game.
Ruinous Path is around to help with multicolored or colorless creatures, as well as planeswalkers.
Sideboard
Clip Wings is in there to help deal with Westvale Abbey
or Dragonlord Ojutai.
Duress is in there to help with creature light control decks
Flaying Tendrils is in there to deal with weenie decks and aristocrats decks.
Grasp of Darkness is in there for additional creature control or to replace Ultimate Price if I am playing lots of colorless or multicolored creatures.
Infinite Obliteration to get rid of someone's best creature.
Naturalize for some artifact/enchantment hate.
Pick the Brain was in the main board but it was moved to the sideboard based upon suggestions and to help deal with combo decks (Seasons Past or the like).
To the Slaughter is for walker heavy decks
Let me know what you think and please feel free to offer suggestions, and as always thanks in advance for your help!
