Welcome to the Official Redemption® Message Board!
I think the two new Dominants are probably the best two they've ever made because of the amount of strategy involved in playing them. They're both very diverse. By comparison, the older Dominants are pretty straight forward, most only having one or two applications. Provided they keep making Dominants like Grapes and Mayhem I hope they continue to make them for years to come. I think it would be good to restrict the number of Dominants a person can use in a deck though because 11 staples is kinda silly.That being said, a Dominant that simply discards a Fortress is too simple and probably won't see print any time soon. The cards we saw in Treasures were an attempt to weaken Fortresses without using Dominants to do it. If they were to print a Dominant that could discard a Fortress it would probably be more complex and diverse than just "discard a Fortress".
