Right now in Standard, it looks like we have a lot of good enablers for some sort of graveyard deck, thanks to cards like Old Stickfingers and Reclusive Taxidermist
Spells and abilities that were targeting that permanent and Auras and Equipment that were attached to that permanent aren't affected unless the new characteristics of the object change the legality of those targets or attachments
Now, Locke and/or the Phoenix could appear in the 99 for Terras Commander deck in MTG , Revival Trance , as it will partially focus on returning cards from the graveyard
It will give a list of mechanics with power levels like 5, 4, 5, 3, and then blatantly lie, claiming those numbers add up to 10
Commander is what I know best, and my lawyers say Im legally bound not to rank cards based on Constructed merit
Whenever one or more creature cards are put into your graveyard from anywhere, venture into the dungeon
