This is my Halloween cube. Cards can be from any set but must be horror themed. It is singleton, meaning there is only one copy of any given card.

Many of the archetypes care about classic creature types like Zombies, Werewolves and Vampires (see below).

Newer players may appreciate a refresher on how Regenerate and 'Splice onto Arcane' mechanics work.

Archetypes:

UB - Zombies
Overwhelm opponents with hordes of undead!

BR - Vampires
These bloodsuckers use Flying and Madness abilities to gain the upper hand.

WR - Spirits
Long-buried ghosts use Arcane powers to create overwhelming value.

RG - Werewolves
When the moon is in the sky, Wolves and Werewolves go on the hunt.

UB - Creepy Crawlies
Insects, Spiders, Snakes and other creeping things that feast upon a full graveyard.

UG - Shapeshifters
Use body snatching abilities to steal your opponent's creatures -- or Changelings to gain power from their Typal effects.

WU - Uncanny Blink
Eerie ETB abilities will out-tempo your foes.

UR - Mad Wizards
Spell-sling with Arcane magic and finish off your enemies with a potent Storm.

WG - Poison Swarm
These Toxic critters will Proliferate your enemy to a poisonous end.

WB - Demonic Ritualists
Evil Clerics performing sacrifices to summon terrible Demons from the beyond.

WUBRG - Scarecrows
Fix your mana with Scarecrows and maybe even destroy your opponents permanents along the way.

WUBRG - Curses
Heap Curses upon your nemeses.

For equal distribution of 666 cards, draft as 18-card packs. Spooky! I've tried to not go too crazy with cards that take a long time to read, but this will be a factor with 3-4 more cards per pack than usual.

You can also draft as a Commander Cube. I recommend seeding 20-card packs with 3 commanders options each, drafting 2 picks at a time. Planeswalkers count as commanders and mono-color legends are all considered to have Partner. Build 60-card decks.

Some questions I have for feedback: Is it too confusing to have werewolves with both transform mechanics? Are there cards that take you out of the Halloween feeling? Are there cards you assumed would be in the cube but aren't?
