In order to push the Fall set back, WotC would have to a) end or greatly diminish the PAX West tie-in, b) have PAX previews four weeks before any other previews begin, or c) extend Fall set spoiler season from three weeks to seven weeks
For Sneak and Show, you need a pair of Intuitions, a pair of City of Traitors, and a couple of dual lands
There are also two types of flair, one that adds an effect over the card called cosmetic flair (like shining stars or glitter, as shown with the Kirlia example above) and one that shows an effect when you play the card in a battle called battle flair (as shown with the Mewtwo card above)
What I like most about this card is that its flexible and lets you spend your mana to draw cards only when you need to
Many people run creatures with 4 toughness, solely with this in mind
