At least in Goblin Bidding, the problem of this card granting haste is pretty irrelevant, since Bidding has Warchief at its dispossal. However, it is also important to note that Goblin Bidding usually wins the very same turn that it casts Patriarch's Bidding. Granting similar functionality at a lower cost and giving creatures haste whether they're Goblins or Zombies will probably yield similar results in any deck where this sees play: the deck wins whenever this resolves.
I subscribe to that assessment. The real problem is the haste ability.
T1-Scenario:
1st t: Bazaar of Baghdad-opening.
1st opp-t: Whatever. eot, mill three huge cc<4 critters into your yard. (Flesh Reaver, Negator, Psychatog etc.)
2nd t: repeat milling, drop Swamp => Ritual => Ebullient Eve for the win.
With the usual tutors around, I could imagine that quite a consistent deck that might easily back up it's plan with FoW or Duress, if required.
