Not Countered if Target is Invalid : Normally, an Aura is effectively countered if the target it was supposed to enchant becomes invalid before it resolves
The set had many things going on, obviously, so the rare cycle of mono-colored artifacts may have gone largely unnoticed
Its also very different in that you tuck the cards from your hand rather than discard them, but thats more of a difference than a downside
With a cheap discard outlet like Putrid Imp, you can pull off this combo using your Sol Ring, Arcane Signet, or any other one to two-mana artifact, too
Core Strategy: Start the game by establishing your mana base and deploying self-recurring creatures like Reassembling Skeleton and Gravecrawler
Sorry, I was referring to this
