This is my cube! There are many like it, but this one is mine.
In this cube, I try to play around a lot with the 6th-12th picks of a pack in this cube. To do this, I have included something that the Lords of Limited have coined as "Pockets of Synergy". Essentially, you will not find themes with enough cards for an entire theme in your deck. Nonetheless, there are cards that work very well together.
For example, there is a Siege-Gang Commander. By taking that card, if you see a Mogg War Marshall later on, you may be inclined to take the Mogg War Marshall over a stronger red card. There aren't enough goblin cards to make a goblin "deck" per se, so you will have to fill out your deck with perhaps other pockets of synergy. You may even find some pockets that overlap!
You can still get by drafting traditionally "good" cards all throughout and do well enough, but it is highly encouraged to pick some cards that will unlock some potential of other cards. Put some thought into your middle picks to take advantage of your previous picks' creature types, abilities, and costs and you will do well.
A few pockets include:
Artifacts (Treasures! Clues! Food! Oh my!)
Sneak Attack (Swing with a Piru and then wipe the field! Stabilize with a ton of life!)
Sacrifice Synergies (Sac your permanents for profit!)
Stax (Sac THEIR permanents for profit!)
Goblins (The funny little guys! Make lots of them!)
Zombies (You can't keep em down!)
Looting/Discarding (Madness in Violent Eruption! Free Rootwallas!)
Clerics (Both the good and the evil ones. Use Rotlung to play nice with zombos!)
Enchantments (Glittering Things! Sythis triggers!)
Top of Library Matters (Predict the Future... Sight. Flip a miracle for profit!)
Soldiers (Make an army!)
Spells in Exile (Go on a cruise and then beat face with a Crackling Drake!)
Reanimator (Get an early Avatar of Woe! Note: Due to power reasons, Recurring Nightmare is the cheapest reanimator card)
B/G Graveyard (Forget Reduce and Reuse! Skip straight to Recycle!)
R Aggro (Hit early! Put them on their back foot!)
Flash (Surprise the opponent!)
Power 4 matters (4 is the magic number! Turn on Rhonas with ease!)
Many of these pockets have several different ways to go about doing it. Be creative and discover!
