mtg summer magic cards GEM MINT BGS 9.5 Magic/MTG Badlands, ULTRA RARE!!! Spells you control cant be countered this turn Weakness Summer Magic / Edgar

The simple rule is, if the card doesnt say you can, then you cant. How Can You Return Cards from Exile

Ichor Wellspring ain't no proper egg in that sense (it has no built-in sacrifice ability), but assuming your deck hangs out with an entourage like Braids, Arisen Nightmare or Daretti, Scrap Savant and you can reanimate artifacts, you can draw a lot of omelets with this one

This card doesnt have the game-changing upside of Ink-Eyes, Servant of Oni, but it provides support for your ninja presence on the battlefield

You'll put a time counter on it at the beginning of your upkeep, and once you have at least one you'll be able to Time Travel (or proliferate) them to either of your hearts' content!
