Here at QS, we love the website Hipsters of the Coast. They read our stuff, we read theirs; it's a great friendship. When HotC comes up with something great, I want to share it with all of you.
Planning to play the prerelease? It might be good to know what might blow you out.
This article has some good graphics that may help, and I think everyone should check it out.

Elsewhere on the internet, spikey players are talking about which color box to take to make sure your seeded pack gives you the best chance of winning. The best discussion I saw was on the spikes subreddit, seen here.
The consensus seems to be that white is the best color given its solid creatures and its superior promo. It's hard to argue. Also, white has a chance at an Athreos in its seeded pack so given all of those factors, white is the clear favorite.
Green has a chance at Ajani (JK, green can only get Kruphix or Pharika, apparently), though, and solid creatures although the promo is lacking. Blue has the best tempo stuff and its fliers are solid, so Green and Blue seem like they are favorites for everyone's backup colors.
Can we really rule out Black? Having so many good removal spells is going to make it a force to be reckoned with. Red has burn and I won the Theros prerlease on the back of some burn, some efficient creatures and a Purphoros, God of the Forge. If they run out of White, or if you are at the prerelease to have fun, there is a case to be made for every color, so just play your favorite. You can't be variance, after all, and a good Black box will always beat a bad White one, no matter how good their promo is.
