Claim (to) Fame
 
It's interesting that many people will probably initially read the two halves of this card as inviting you to use both on the same creature, even though of course there's no real need to. In larger card pools, there's almost as much advantage these days in reanimating a cheap creature as a huge one (think Noble Hierarch or Dark Confidant), especially for such a low cost. I don't think there's been a new version of this effect that was so cheap since the days of Exhume and Life/Death, and I don't doubt it will make an impact in numerous formats.

Claim//Fame (8/8)

These split cards are certainly a unique take on the mechanic: you get one half in your hand and the other half from your graveyard. There have been a number of these to have some impact, but Claim//Fame is the most promising one in Hour of Devastation off the back of its hand-cast iteration, Claim, which functions as a slightly weaker Unearth. This is definitely a bigger deal in Modern when you have a lot of good, cheap creatures for two or less mana (like Death's Shadow, Dark Confidant, and Tarmogoyf), and it’s not all that bad in Standard. One-mana reanimation with no steep penalty is always worth looking at, and there are enough creatures that Claim is excellent value.

Fame is less “exciting”, but it's still a nice surprise that can catch your opponents off-guard. It makes Claim//Fame a three-mana massive swing, or it lets you surprise them later by using Fame to give something scary haste and a bit of a buff. While Claim definitely is the main attraction, Fame is a nice upside, even if it won't get cast nearly as often.
