Grimoire of the Mindless Legendary Artifact At the beginning of your upkeep, if you control a Zombie, you may put a study counter on Grimoire of the Mindless. , Sacrifice Grimoire of the Mindless: Put the top X cards of your library into your graveyard, then search your library for an instant or sorcery with converted mana cost X or less and cast it without paying its cost, where X is equal to the number of study counters on Grimoire of the Mindless.
I was fiddling around with Grimoire of the Dead and wanted another big 'ol zombie book for my zombie-mill. This would be fun to search for, say, Traumatize , or even just a Mana Leak when they try to cast something. The only prblem is i could see it being broken if it allows you to cast sorceries at instant speed, which im still trying to figure out if it actually does or not.
You cast the card during the resolution of the ability, so you do cast the sorcery at "instant speed". If you don't want that, you can word it like Mind's Desire or Sins of the Past .
But, if this is broken it's probably because of the same reason Cascade was so good, cards like Hypergenesis or Living End .
