Avacyn Restored Ignite the Dawn will be a large stand-alone set of 244 cards and it will be drafted by itself
It could be hard to fit it into an Omnath, Locus of Creation deck, for instance, but most decks with three or fewer colors should be able to find room somewhere
You can open these cards in Set, Draft, and Collector Boosters, in both non-foil and traditional foil
Thor is the safest bet for Standard play
it helps me figure out when its worth grabbing certain splashable cards or off-color fixing lands
A Gray Ogre is just abysmal, and while it has a decent activated ability that can make it a 4/4 with Haste, I dont think this does enough to be saved from being a card you cut significantly more often than you play it
