I personally like it as a utility mechanic, and while the sheer ability to create tokens when the creature dies is present in tons of cards from tons of sets, I like the flavor and feel of it being called afterlife
As if that wasnt enough, theres even the brand-new Izzet Elementals shell, which has been putting up an incredibly strong performance
BUT if the strategy/theme involves untap/tap effects like Intruder Alarm & Faces of the Past, this card makes more sense (although it still needs haste from Lightning Greaves)
And so far for Edge of Eternities, it looks to be Kilo's Counter Intelligence deck
While high-cost Spacecrafts like look hard to cast, they're much more appealing with a few copies of Red-White Space Stations Green-Blue Ramp Green-blue decks have a secret: they can play four to five colors
This card was insane, and it certainly deserved the ban
