You don't need the great furnaces just for the Ancient Grudge in the SB.
Go with:
-4 furnace
-2 nexus
+1 Tree of tales
+4 Darksteel Citadel
+1 Glimmervoid / City of brass
If there's no Wasteland/land destruction in your meta:
-4 furnace
+1 Tree of tales
+2 Darksteel Citadel
+1 Glimmervoid / City of brass

4x Master of etherium is needed. The card is the bigger beatstick in the format (beside sometimes maybe Crusher/Terravore/Dreadnough). Cut 1 Enforcer or 1 Drum for it.

Ancient grudge simply sucks in the format due to the low number of Affinity decks and the high number of problematic Enchantments. Krosan Grip is on-color and the best solution for those.
