Singleton cube containing cards released before Mirage block.
More modern ratio of creatures : spells in all colors.
No: Banding, snow lands
Avoided: Cumulative upkeep, extreme color hosers
Very loose archetypes:
: Flyers, powerful symmetric effects, swarm
: Broken cards, flyers, stealing
: Reanimate, sacrifice, zombies
: Big mana, burn, goblins
: Beef, ramp, swarm
Thallids aren't working. Also unimpressed with faerie tribal.
Time to try some other options for green - a little more artifact removal options, a little more beef, a few more options for dealing with flyers.
