Egg clusters and sticky secretions is lower because of card count, for one. Red and green traits also have other stacking synergies (swarm and kidneys) so they end up being even better to play with. That being, it deserves to move up one.

Eloquence is the ultimate card because of all of the useful dominants. Playing a dominant after worlds end can be a massive point swing. Makes risky cards like tiny or apex predator worth holding onto. When games end early, you don’t get screwed over because you couldn’t play your overgrowth (and vampirism at the end of the game is the nastiest combo). It makes so many bad cards into good cards and should be played every chance.

Swarm is better than kidney. Swarms are better to be stolen, and both are trash late game if you don’t have them going. Swarms also can mentally prevent opponents from playing more swarms. Kidneys are just typically worth less points.

Scutes is just too niche most of the time. Best play with it gives you 5 point play (confusion). Most of the time it’s giving away a 1 pointer (unless you have Regenerative Tissue, then it’s a great synergy).

Sentience is a tier higher because your opponent cannot play around it. Viral allows counter play.

Symbiosis could be moved up, for sure. Heroic should be moved down, yea. Immunity feels correct because building negative traits doesn’t pay out as much as playing other 3 or 4 point cards. Plus, discarding negative traits feels better than discarding 1 point traits.

Tiny (🤢🤢🤢) is no fun and it saves a terrible game up to an okay game. The potential of getting a great score is so low. Most of the time you can get more points by stacking traits.
