This kind of eternal roadblock has been around in design tinkering since Gate has been released.
A 4 mana 0/0 that can’t be affected by anything (including buffs and death) seems quite compelling, but I am sure it could be too good if you can lock yourself into a corner against a general that doesn’t use ranged damage.
Space poet:
3 mana
Legendary
3/4
Cards that draw cards can only draw cards that draw cards when they draw cards. When a card that does not draw cards is drawn by a card that draws cards, draw a card.

The second sentence makes no sense with the clause from the first one…
It’s space poet, not space linguist you Baka

I can’t believe I forgot about the basic cards. 
Huge update. I finished the Epic cards and relocated many of the card rarities to follow the template @akurane gave me. (Thanks! Many thanks to all of you who gave me inspiration as well.) I also made some new cards in the Rare and below category. These include:
Finished the legendary minions in the Core set. Time to work on Shim’Zar!
remember to make at least 1 stupidly overpowered card for each expansion and flip a coin to see if it gets nerfed.
Of course. 
critique time
pathfinder is a little too similar to OG abyssal crawler, just +1 mana with flying
satelite oprrant is basically a healing mystic with its og replaced with aerial rift
with those tiles is there even a point to having airdrop on anything in this faction?
interspace is literally just anti-zeal. doesnt feel unique
penumbra… feels like you could change its effect to dying wish and change nothing
anomoly… too much damage potential for 1 mana
infection needs to swap lines 1 and 2 so its clear that it checks for parasites before giving them one
wormhole is way too strong for 1 mana. especially since it doesnt say “until the end of your turn”
oddity is good. feels a bit too much like sanctify though
cerebellum-chirpuka? is that you?
beacon- is it a structure?
bloodsucker feels very unfair. its an immediate effect that wins games for 4 mana and has basically no counter. parasite should not be paired with “when taking damage” or similar things
juggernaut- +2/2 is way to big a buff for a 3 drop. its too swingy.bring it up to a 3/3 and cut the buff to +1/1
origin feels fine
malfunction feels wrong. but i guess its ok.
gravity sphere feels too powerful. it should target a specific parasite instead of doing it around all of them.
oort cloud feels fine
astrographer would be more interesting if it only got the buff while standing on the tile
is broodmother a structure? i just gotta ask
engineer looks cool. its also a win condition on par with jax razorback but could safely be bumped up to 7 mana
link needs to be nerfed. 3 health per attack is too strong especially for 1 mana
hive seems alright
virus is a cool card.
hyperparasite- grailmaster? is that you?
observer is too beefy to be ash mephyt 2.0
rift could be 3 mana and feel fine since its basically choking tendrils+essence sculpt
supernova = obliterate
enigma feels ok… maybe
disrupter is bonkers. when it breaks summon beefier jax?
lightworm feels like a sentinel trying its hardest not to look like a sentinel
quasar is too strong. drop the transform down to 1 since its literally replacing random enemy minions with detrimental minions. its better than even simply destroying random minions since the parasite minions are so harmful to the owner.
alpha is OP. potentially summoning 8 8/8s is broken. the staircase effect is nice but instead of increasing stats just keep the effects interesting and maybe throw in some detrimental effects
grandmaster just doesnt feel AWESOME enough. and it doesnt affect the enemy general in a unique way. its basically an aoe infest with limits
universe is a good payoff card. could do with a smidgen less stats, but its fine.
old god is just unfair. even doom has some ways to comeback or avoid it after played. literally writing “you cannot lose” is just toxic. although
it DOES kill your general for playing it and it says NOTHING about it becoming your general 
railgun- you might at well make it simpler and write +2 attack ranged celerity celerity cause thats what i read. maybe specify that it has to be 3 different targets, cause otherwise thats just 12 free face damage for 1 cqrd on 7 mana.
At first: Great job!!!
Like the idea and the approach! Probably I’ll do smth myself now.
Also I think the a lot needs to be nerfed as it is kind of strong (bbs teleporting enemy minions plus give all your minions a limited airdrop while removing tiles and can’t be cornered… ouch) but I think it’s hard to balance a project of that size proper.
So dude I love the idea.
Going a little bit off of what @oranos said (mainly focusing on legendaries, will probably edit or comment later for the rest of the core set):
old god really is terrible design. i mean what if both players get one on the board. itll just go on until someone gets bored and quits
Platinum Angel + Abyssal Persecutor
Call for judge, get stuck staring at opponent for all eternity.
Path to exile.
Done.
Or in dooly terms
just use dispel damnit
Yay a faction concept!
Great work pal, it is alot of work to put something like this together! Great effort!
I really like the conspet of an acient alien race, with lovecraftian shapes and hybrid organical/ mechanical beings. My initial idea of the last concept i made was something similar, so i realy liked to see a concept like this!
I realy liked the parasite keyword, and the thought of giving your opponent minions with negative effects is something i have wanted to see.
Vortex Hyperwarp is also a mechanic i realy liked, the idea of moving a minion from anywhere to a certian place is appealing to me.
Interspace I feel is somewhat lacklusting. To me it is not unique enough to be a keyword, and also realy simple to pull off? So i have a suggestion,
Interspace/: Whenever this minion moves away from your general activate an effect.
OR Spacebend: Whenever a minion moves next to this minion, activate an effect.
Card example:
arcane slinger (rare)
3 mana - 4/1
Interspace: Gain ranged until end of turn
Acient behemoth (Epic)
8 Mana - 8/10
Spacebend: If it is an enemy minion, attack that minion.
I have not looked enought into each card as a set and will give more feedback when i have looked it over.
Amazing job! Appreciate the time you did to make this!
gravity well is already a card so while the effect is good, the name needs a change
WOw, great job! but to me the “interspace” mechanic must be " whenever not nearby anything" to be balanced ^^
Shoot, you’re right 
Changed it to Spacebend
