I'd like to work Attrition in here.
-1 Snapcaster Mage
-1 Power Artifact
-1 Decree of Pain
+1 Phyrexian Altar
+1 Rings of Brighthearth
+1 Grim Monolith
Rings are more useful outside of the combo than Power Artifact, and Phyrexian Altar helps us make colored mana our of our dorks to start Oona mills.
