I forgot about his ability.
Essentially, that quest boiled down to the luck of the dice roll for me then. I could only win if the heroes were unlucky in the end because Mok could just force me to discard my most useful card. Strangely, the heroes haven't used Mok's ability yet.
So now I have to do The True Enemy, which the heroes only have to kill Mirklace to win. That shouldn't be too tough for them considering how much damage heroes can do. It looks like I could use Kobolds but I'm not sure I understand the ritual groups. Could I pick Kobolds and Goblin Archers, place the Goblin Archers as the ritual group that gets the master and the Kobolds can refresh up to 6 minions?
Knocking down Logan Lashley is a good strategy if I can catch him alone like I did in the last quest. He's relatively squishy as he has no means of defense and no health buff. I purchased Mistrust, so I could use that to prevent Elder Mok from healing him. Elder Mok has a shield so it'll be more difficult to knock him down. Durik can use the wolf to add brown die to each hero and Jaes already has an armor (already rolls 2 gray dice).
If the heroes are smart, they will try to kill Rylan quickly to avoid giving me reinforcements. The Kobolds make it a great way to test and pass the summoning because I can get them back quickly (Deep Pit). I figure I'll get 2 turns before they enter the Town Square. They'll probably make Jaes and Durik/wolf tank up front. Rylan will probably die 2 turns later, so I'll probably end up with just 3-4 fatigue tokens. I'll have to use the Kobolds/Ynfernal Hulks to do the killing and they should focus on killing just 1 hero twice.
I'm probably going to want to hold on to cards that add damage and allow for more attacks (critical blow + frenzy + fatigue spend on Mirklace hits hard and heals well).
