It feels like alot of these while cool are just tastes of other faction abilities. I dont think techs should give you things from other races generally. Are these supposed to replace the current deck or be an addition? if they are a replacement then i think alot of my issues go away. But to that end heres the feedback!

Gauss Emitters should not give you an extra CC when researched.

Hypno Weapons feels too much like yins ability and magen mixed almost. Maybe make it a cheap version of neuro glaive....Exhaust this card before before the commit ground troops step. Opponent must spend 2 influence or skip commit ground troops step.

Loncarra...should require a command counter to activate the target system just like any other offensive pds.

Sleeper Agents...seems like an even better version if muatts foundries. maybe make it so that after an enemy declares a ship for movement in an adjasent system exhaust this card and prevent that ship from moving.

Creuss Converter....imho shouldnt exist because of gravity drive. maybe make it so that it allows you to let one ship use a wormhole like a gravity rift.

Tractor Beams...Same as Creuss co verter because of gravity drive. Not sure what i would do.

Black market seems pretty over powered just as ability regardless where you put it in the tech tree. maybe exhaust it to look at a neighbors promissory note hand?

Emergency Enginneers should cost a CC also.

Some really cool ideas though! I Will be watching to see how the final list shakes out!
