Archfiend of Ifnir

Oracle Text
Flying
Whenever you cycle or discard another card, put a -1/-1 counter on each creature your opponents control.
Cycling
( , Discard this card: Draw a card.)Card Rulings
4/18/2017 Some cards have an ability that triggers whenever you cycle any card. These triggered abilities resolve before you draw from the cycling ability.
4/18/2017 An ability that triggers whenever you discard a card doesn’t give you permission to discard cards. You’ll need another effect that instructs or allows you to discard them.
4/18/2017 An ability that triggers whenever you “cycle or discard” a card triggers only once if you cycle a card. The ability “Whenever you discard a card” is functionally identical to this ability; cycling is mentioned for clarity.
4/18/2017 If a player discards a card during their cleanup step due to having too many cards in hand, any appropriate abilities that trigger on discarding that card trigger. If this happens, those triggered abilities are put onto the stack and players receive priority in that cleanup step to cast spells or activate abilities (normally, no players may take actions during a cleanup step). Another cleanup step is created following that one.
Edit: Just realized that Collective Brutality will also be standard legal.
Yeah, I like this card.
1) It puts itself in the GY for reanimation
2) It has Synergy with self discard like LotV, smallpox, and Zombie Infestation
3) 5/4 Flying for 5 is very respectable.
4) No Downside (which is a big deal for a demon)
I want to try putting it in Modern Loampox or something similar.
You cycle it, put it into play with End, then kill your opponents' creatures when you cycle other creatures.
Plus, it flies. Disgusting.
I can't count the number of times I've had to explain the difference between Menace and Skulk. To an experienced player, they're nothing alike. But, to newer players, they are very similar. They both create a limitation on blocking. Another example is Goad and Provoke, which should never be in the same set as both words have essentially the same meaning. Poison, Withering, and Infect in the same set would be a nightmare for new players.
So, Cycling and Sacrificial-Cycling (or whatever) would be highly confusing. And then there's the fact that if that happened, they'd be drastically changing the meaning of "Cycling", which seems to me like a bad decision.
My bet is that there will be cards printed that cycle from play, and you'll have to sacrifice them to draw the card. Essentially, they would work like the cards I linked from Urza's Destiny, but will actually use the word "cycling," so to trigger the Archfiend and others worded like it.
This means that unlike the Urza's Destiny "sacrifice-to-cycle" cards, which did not trigger cards like Astral Slide, there will be cards that do trigger them. If the Archfiend only said discard, it would not work with the "sacrifice-to-cycle" cards; if it only said cycle, it wouldn't work with discarding cards. This way, all scenarios are covered.
"Also by not directly tying them to cycling, they did not work with the cards to come that cared when other things were cycled."
I don't see how this has any relevance here. Archfiend isn't Cycling. It just triggers off a Cycling effect. The only way this could matter is if there is a card that says something unbelievably specific like, "Whenever a card with "Cycle" in the text is triggered, trigger it again". Or, I suppose, "Whenever you Cycle a card, abilities that would be triggered are instead not triggered." Though, in that case including "or discard a card" still would have no effect.
The more I think about this, the more I talk myself out of any possibility that there's any purpose to the extra text.
Adding the "you cycle" part is redundant because cycling is already discarding. It only becomes non-redundant if they came up with a new variant of cycling that doesn't discard. MaRo mentioned years ago that the Urza's Destiny cards Yavimaya Elder, Slinking Skirge, Plague Dogs, Marker Beetles, Illuminated Wings, Heart Warden, Capashen Standard, and Brass Secretary, were supposed to use the word cycling, but for some reason they weren't.
I'm expecting that we get something like that either in this set, or in the next one.
EDIT: MaRo is the lead designer of this set.
Relevant text from the article: "We talked at the time about putting something on the card to reference cycling but everyone felt that the cards were much cleaner written as is. They were, but what got lost was that no one ... saw these cards as having anything to do with cycling. Also by not directly tying them to cycling, they did not work with the cards to come that cared when other things were cycled."
That last sentence is important, because this phrasing specifically makes sure that those cards would trigger when being cycled.
Edit: One upside the Zombie had is that it had Etb for itself. Other than that, outclassed.
