Since I like figuring these things out, inkmoth nexus + hatred would clock in at 2 cards, 0 chaff, and 7 "mana" when you count the foregone opportunity of tapping the nexus. Also, it appears to be vulnerable to almost every possible hate card category: land removal, creature removal, artifact removal, counterspells, pithing needle, meddling mage, and gaddock teeg to name a few. I wonder if a two-card combo exists which is also vulnerable to enchantment removal and graveyard hate. It would be kind of interesting to come up with one that was vulnerable to everything.

I'll also add that hatred, even on its own, is very dirty in EDH.
