I had an nice idea today about a nedly card:
Innocent spy
event, House Stark only
Any Phase: Look at any players hand and discard a cards from that hand. Then choose and kill a character you control. If you control Bran Stark you have to choose him.
That led to an other idea of a good, game changing card, but not broken with some choice.
Open battlefield
location, 2 cost, neutral
Limit one per deck, No Attachemets
Challanges: Kneel Open battlefield to look at any players hand and discard a card from that hand, then discard a card from your hand.
Any Phase: Kneel 6 influance to shuffle Open battlefield to its owner deck. Any player may trigger this.
and finally I had an idea about a plot for Greyjoys
Help from the Drowned God
3/0/1 - House Greyjoy only
During marshaling phase this round you may pay X gold to discards from play up to 3 non-limited locations with combinated printed cost X.
