If you look at the first two builds mentioned in this thread, the build mentioned by CorruptedAngel uses it as a one-of.
My 2 cents on the card is that its a win more card. From my testing, this deck has slow start but a very high top speed, reasoning being that it takes 3 mana sources to really get going (matron, warchief, ringleader if warchief is played the turn before, etc) but this deck can come out from a bad position and just overwhelm people with hasted piledrivers if the mana permits. Kiki jiki just makes your good board position even better. In that one-of slot I perfer the Pyromancer. Gotta love mad jail breaks, and it messes with people's math.
