1 card : 1 card + 4 gems - First-come, first-served (like in queue)
or
1 card : 1 card + X gems - The more gems in offer, the higher place in the queue.

If you don't have gems, don't worry I can accept cards / marketable items from Dota 2 or Counter-Strike: Global Offensive / emoticons / profile backgrounds / Steam Summer Sale 2017 cards (aka Mysterious Cards) instead of gems.

I also accept mix trade offer in which you propose me exchange 2 cards from I game & 4 cards from II game, etc.
But remember I accept only exchange from the same set, so in above example I should get 2 cards from I game & 4 from II, etc.
