The Maw 27 abilities: 

• Can absorb anything it wants like a normal black hole
• Can choose not to destroy everything it touches (like me)

• Is a Fullborn
• Being bonked by it is very bad for your soul

Maelstrom abilities:

• With one steel: Eliminate all cards from the Market
• With more steel: Eliminate all opponents' Allies

Advanced Military abilities:

• In conflicts, I may choose to remove tokens from areas adjacent by land. After each round of token removal a new check for token majority must be made. I may decide to wait for other token conflicts to be resolved first
• In the event of Civil Disorder: Reduce 1 less city.

Haustorium abilities:

• Gives one green cube when unpromoted
• When promoted, I must pick between Parasitic Plant (skeletal number becomes 0) and Parasitic Fungus (skeletal number becomes 5, and I get a mutualism bonus)

Green Parasite abilities:

• Can be deployed as either Salmonella or Cyanobacteria
• Steals a blue and a yellow cube (Salmonella) or blue and a red cube (Cyanobacteria)
• Does double oxygen spike (any organism in the same home row with less than two oxygen resistance must atrophy)
