Although the format is currently designed to be midrange heavy, there’s probably room for a very fast deck. How many 2/1 for one are there right now? Quite a few.
Supposing we want to be an ultra fast white deck that goes wide, we can use all the one drops available to us:
Sadly, that’s all the one-drops worth their salt. I guess 23 is enough. Some sort of Anthem effect would probably be nice. Spear of Heliod comes to mind as not all of these share a creature type (so Obelisk of Urd is out of the question).
