Hello
I have been playing Dominion for about a month on this website now and I have never played with "Possession". Is it just bad luck or is it normal ?
It is banned from the ranked match making queue.
If you are a subscriber and have access to Possession, you can create a table and include Possession as a required card. Possession is not be added to any cards randomly added to a game (the rated automatched selects all cards randomly, and therefore never includes it)
