You may have any number of bands, all creatures in a band attack the same thing, and a creature cant be in more than one band
COMMANDER DAMAGE: Any player thats been dealt 21 or more combat damage by the same commander over a game loses the game
Not worth it by a long shot
there hasnt been a good Jund Dredge commander since well, ever (you can do dredge stuff with The Beamtown Bullies, but that deck will play very differently than here)
With enchantment cards, Manifest Dread, and various other ways to enable graveyard filling, there will be lots of opportunity to benefit off Delirium in this set
Still valuable in high grades, but worth considerably less than Shadowless equivalents
