I think you have to edit/save the deck before it will show that. I don't think the deck lists are dynamic (meaning they constantly check for legality). Rather, they check at each save. Thus, if you haven't "edited" (opened the edit feature) the deck in a long time, it will be "frozen" as a snapshot of whenever you last hit the save button from the edit screen.

Ah, yet another deck that has fallen victim to rotation!

Oh, this isn't Standard legal anymore!

Bookrook, thanks for the upvote and suggestions! I will probably include 2x Unstoppable Slasher.

Come Back Wrong is interesting, but I think very situational. Because it is sorcery speed, it would be good for a creature with a good ETB effect, but otherwise paying that extra black mana is just a bit slow. With Gruul Prowess and several midrange decks jamming the top-played decks, I don't think there are many good targets that would consistently show up that are worth the extra cost of this sorcery-speed spell or worth having just until the end of our current turn. We'll see how the metagame shapes up in the next few weeks, though, as Come Back Wrong might be an interesting sideboard tech.

Overlord of the Hauntwoods doesn't fit very well. We're not really trying to ramp into larger threats, and we already have Sheoldred, the Apocalypse (with deathtouch!) and Aclazotz, Deepest Betrayal  ^Flip at the top of the curve. I think both of those pay higher dividends in this particular type of deck than the Overlord would. In this deck, we're more about efficiency with creatures and removal than we are about trying to jam large creatures out ahead of schedule. Overlord, then, is probably not the best fit for this deck.

Thanks again for the upvote and for the suggestions!

Balaam__, yeah, it sucks-- but at least Standard is in a fairly good place.

Oh, but rotation happened, so this isn't Standard legal anymore!

Fun deck!

+1 from me!
