WarHammer 40,000 Commander

This is a special set snapshot as there are no specific cards listed. Instead, consider constructing a cubelet that is comprised of cards from each of the decks as well as any future Warhammer 40,000 cards from Secret Lairs. You could make it perfectly balanced and select 25 cards from each deck or you could just pick the  100 cards from the entire Warhammer 40,000 Commander pool. If you want to make this feel more authentic to factions fighting factions, you could consider assigning a faction to each player and they can not play that faction as lands.

Generally, consider your ratio of removal spells to things to do as you build this themed cubelet. Searching the library is usually frowned upon because the library is shared, so you could gather information about what cards are in hands or played as lands. There are more thoughts on the construction of a cubelet here.

All in all, this set offers quite a bit of cards that would be a lot of fun to jam together and fight it out as a themed cubelet. If they don't search the library or do something you normally can't do in Cubelet, they are very fair considerations for any of your cubelets you have. Another reason why specific cards are not pointed out from this set.
