Took on Incarnate with a 4-card upgraded scarab deck. My bone wall got up to about 51 shields, and I was going to win until he pulled out his own bone wall. Then everything went downhill from there (since he kept on getting shields when I devoured his skellies)
Looking back, I might have been able to win if I hadn't continued eating after he put down bone wall.
I had 2 more epic battles earlier today with him >.>
Each of us had several boneyards/graveyards and I had like 10 scarabs up and my own bone wall.
We both had hundreds of walls (Sundials and RoF ftw), and the rest of our screen completely skeletoned. My scarabs were each like 30|40 or something.
Every time he pulled out a retrovirus or a special creature, I ate it and out popped like 7 skeletons. Eventually, I ate all his creatures, killed his shield and the next 5 bonewalls he put up, and killed him in 1 hit
