The Tnelis Syndicate

 

Abilities: Grab 2 secret missions and keep one. Can complete 3 secret missions. Even if ships get destroyed in combat you can still invade with ground forces afterwards. 

Flagship: One ship from opponent rolls one less die (your choice)

Nice. I wish you could complete 4 secret missions, which would be double the normal player but I like the idea of a spy agency faction you get to play with. Some of the powers would be interesting to play with here. I like that you can still go after the planet even if your ship is destroyed. A strategy I would try is just send a carrier packed with mechs and troops to take a planet someone controls. 

Depending on how you play with them, they could be one of the biggest threats in the game.
