Would you think Kiki-Jiki or GriselBrand would be good in the list?
Kiki-Jiki is out because he is useless without a combo piece. You could win straight out with a successful X=2, but the combo would be just as disruptible as the traditional kiki resto, you would be better off simply playing a kiki resto deck which fields creatures that work with both of them, such as wall of omens or snapcaster.
Griselbrand might help you stabilize against aggro decks, but that's not good enough to field as a main. The creature in question should be able to protect itself first and foremost, and then also be able to close the game in as little time as possible. Iona and Emrakul both fulfill these requirements, hence their position in the main.
Given the current meta it probably isn't crazy to field Griselbrand in the 75. If you expect tonnes of mono red then its plausible to even main him.
Makes sense and I know kiki is probably a little fragile. The griselbrand is interesting because of the life gain and card draw. You could potentially set up your next turn very easily depending how your deck is built.
