Hello, I'm new here, but I've been playing the COC LCG for a few months now, and I've been reading up on some of the problems that have been arising due to Agency/Hastur Magah Birds, 70 steps, and endless interrogation combinations. In card games, I generally find banning cards to be a last resort, but I think a good errata for a card can bring it more into line with game balance. So as a suggestion, I'd like to present my new text to Magah birds.
Magah Birds
Faction Hastur
Cost 1
Skill 1
Text - Fast.
Response - When Magah birds is put into play, you may drain up two two of your domains. For each domain drained in this way you may put one character named Magah birds into play from your deck.
I think that this solution forces the Hastur character to choose whether or not he wants to run Magah birds or 70 steps as a turn one play without significantly hurting the playability of Magah birds (It still gets you 3 characters with fast on turn one without compromising your card advantage.) It just forces the Hastur player to make a difficult choice in how to make his turn 1 and 2 plays for his benefit, and also gives the other player a chance to counter. Hastur/Agency would still be quite powerful, just somewhat less powerful.
suggestions and feedback are of course welcome, as I'm sure there are a great many peopel with more insight into the issue than me.
