Fast: if the conditions written on the card are satisfied play again (you will get the normal production as for swift cards).

Some exemples:

Tower rebuilding (common)
Cost 6 bricks
Fast (tower < 15)
tower + 5

Ornitotter (uncommon)
Cost: 5 recruits
Fast (enemy wall < enemy tower)
enemy tower -4

Exorcism (common) (holy)
Cost 5/5/5
Fast (holy cards in hand >2)
Discard an undead card from enemy hand

Merchant's gift (common)
Cost: free
Fast (stock <10)
stock +1

It has a kinda something I suppose.
Though I believe Ornitotter is to expensive. Compare it to Heavy infantry. Instead of a conditional swift, it gives choice, and is 4R cheaper.

Yes, you are right, now I edit it. anyway I've just made some examples to show the keyword's potential, I didn't meant to create new (bilanced) cards.

the current omnitor isnt expensive at all imo, the conditions are easy to reach, so it cost 5 recruits to get a turn of production, play again, and do 4 tower damage. its too good imo

If you read the 2 posts prior to yours better you'd see it's edited.

anyway I think the Idea is great... exept the normal production again... that's just to powerful, another turn would be enought since it's also very good to have the option of playing another card afterwards.
just a quick card + condition

Kind of hard to implement... We would have to create a condition parser for keywords :(.
