SOI has a good bit of Build Around Archtypes, if you lucky enough to pull one in sealed with support you can go all-in.
This deck went 4-0 (8-0) and all games but 1 came down to winning via Non-combat damage.
I personally thought the deck looked to slow and would die to any form of a curve, so scared i built b/r MADNESS default deck if i faced Hyperaggro. I was granted lucky pairing of control and midrange decks

Creatures
1x Thraben Inspector
1x Rattlechains
2x Manic Scribe
1x Erdwal Illuminator
1x Daring Sleuth/Bearer of Overwhelming Truths
1x Moorland Drifter
1x Stitched Mangler
1x Dauntless Cathar
1x Wild-Field Scarecrow
2x Silent Observer
1x Emissary of the sleepless
1x Drogskol Cavalry
Non-Creatures
1x Explosive Apparatus
2x Puncturing Light
1x Not Forgotten
1x Press for answers
1x Ghostly Wings
1x Fleeting Memories
1x Sleep paralysis
1x Tamiyo's Journal

So majority of games were me landing Tamiyo's Journal on a stable board, and usually DT's either right away or within 1-2 turns for either Fleeting Memories to get the engine going, or Erdwal Iluminator to get the Card advantage flowing.

The preferred curve out is Erdwal into Fleeting Memories make 2 clues, into Silent Observer to D-up into Journal, untap make 2 clues DT for a clue generator , repeat this process once and they were usually milled out,
The card Not Forgotton I've heard lots of pro's say it's bad and I do agree however it worked like a mill card when I could put a Manic Scribe on top , sac a clue to draw it and maybe gain 2 life, and some games I needed to play that manic scribe to mill the last couple cards. Obviously Drogskol Cavalry was a bomb, usually just making token chump blockers and gaining life until the combo can come online and mill them, It saved me from certain death multiple times.

round 1
A sweet Blue Red spells deck with Thing in the Ice, Devil's Playground and the Enchantment Fevered Visions a double sided sword for my opponent however did do roughly 20 damage to me the entire game.

round 2
G/R wolves

Round 3
G/W Human Control, Multiple Rares and he had the Mythic Descend Upon the Sinful which proved to be more hurtful game 1 since he was sandbagging hard making me believe he had situation removal and lands and hand when it was creatures. and not realizing it was playing into my plan, he only pulled the switch when he seen Fleeting Memories.

Round 4
U/G Raging Clues, My silly opp had other clue matter synergies and a Tamiyo's Journal that he left in the board, after the game 1 shellacking he seen the power of what triple Demonic Tutor did that game and sided into similar rares he had. We had a good game 2 I was able to Mill him the turn before a lethal attack.

Initial thoughts is If I was able to build a synergistic deck with a build around card in sealed I can't wait for draft. Also SOI looks really sweet I regret not playing Magic during the 1st Innistrad.
