Scylla, Man-Eater

When Scylla, Man-Eater eaters the battlefield, sacrifice up to six creatures. Scylla gets +1/+1 for each sacrificed creature. If one or more creatures were enchantment creatures, Scylla instead gets +2/+2 for each of those creatures.

"Drown in your sorrow and fears. Choke on your blood and your tears. Bleed till you've run out of years. We must do what it takes to survive."
-Scylla (Epic: The Musical)
