Meadbert - what type of player has been playing Ritual Gifts? Pithing Needle is in the board against ichorid. It doesn't appear you know Ritual Gifts very well.
Nobody around here plays Ritual Gifts. I was two fisted tested so it is possible that I was playing it poorly. I still stand by what I said. Leyline of the Void almost certainly wins game 1 since Ritual Gifts cannot counter it and has no realistic way of goldfishing on turn three with Leyline out.
Chalice is less effective versus Ritual Gifts. Unmask can be more effective. Still these are speed bumps.
Any of the following are very likely to win a game versus Ritual Gifts in game 1:
1: Leyline of the Void
2: Turn 1 Unmask followed by turn 2 Therapy
3: Turn 1 Unmask,CHalice
Games where you only have Unmask or only have Chalice you are in a bad position to win. Ritual Gifts should win the majority of these games.
Games where you have no relevent disruption you should get run over on turn 2/3.
Out of the board Pithing Needle is pretty good. I was running a list I think you posted that had 0 Tormod's Crypt, 3 Pithing Needle and 1 Fire/Ice. Fire/Ice is actually very good in Ritual Gifts versus Ichorid because it basically functions as a Time Walk and that extra turn frequently makes the difference.
Duress is total trash versus Ichorid. You make a good case for why it is good when you are on the play. The problem is you should already have an overwhelming advantage in game two on the play anyway. The relevent game is usually game three when Ichorid is on the play trying to play through hate.
