Sealed advice

[Kaworu, the Fifth Child]

Sealed is slower compared to draft.

For that reason, I recommend that you run 18 lands and play second. When the format is slower, it's more important to hit your land drops on time and draw the extra card vs going first.

You're back. Hey there.

This seems like possibly good advice though seems counter intuitive to my draft brain (who runs 17 almost always)
Is it because I'm not picking my cards and your saying that due to that the deck will be less cohesive and therefore need a bit more time to get rolling?

If this is true should I try to aggro the crap out of everyone giving the card pool?

If you can pull off an aggro sealed deck you should slaughter. Just make sure you don't run out of steam and have a plan for latter game. As I said my B/R aggro draft deck was my best one.

 {Shadowcloak Vampire} can be a game changer in sealed/draft. Forces your oppenent to deal with it thanks to ability to go to the air.

Watch out for {Congregate} it can steal games from you pretty easily. The paragons are ok but generally not worth it.

{Generator Servant} and  {Krenko's Enforcer} are both great commons If you're running rakdos.  But watch out for flying. Blue and white get moving with fliers pretty quick in this format right now.

I've found that green is weak unless you get Nissa or {Yisan, the Wanderer Bard}.

B/W performs well. R/B is good too. If you get a  {Resolute Archangel} play it. The format is slow to get moving but is really good at slowly plinking you down on life.

Blue is good for splashing unless you are loaded up on fliers/control.

(All the other bombs people mentioned are obvious so I didn't cover them)
