My list isn’t too exciting, I just cut a couple Dark Petitions for Talismans to see what would happen. I left one DP in because just thinking about it I feel like Wishclaw Talisman is conditionally better and conditionally worse. After playing with it I still think that. Playing and activating Talisman on the same turn (for 3) seems solidly worse than DP. I think the real value would be in running out Talisman early and then activating it a bit later, but that opens you up to interaction.
Not sure what I’ll change for the next time around. I went 3-2 in a league with it.
