I never had much faith in supernovas with time mark, but I should probably try it before I knock it xD
I'm debating between removing feral/switching it with a shard. I've been absently using it as bait with gods with permanent destruction to protect shards (not sure if it's targetted before hourglasses, but maybe?). It has helped me overcome Scorpio poisoning, but not sure where else it could be useful.
Oh, the deck's fully upgraded too.
Edit: I think I'll leave the feral bond in to help with EM's/permanent sacrifice. I'm loving the addition of sundials, though!
