Can't wait for the next chapter of this text box to be released! pic.twitter.com/TauEpJSycw— Ari Lax (@armlx) September 11, 2018
And he's not wrong, there's a lot to process here. Honestly, my first time reading it really did feel like reading a short story:
"Oh no, a 6/6 hexproof for only four mana? This could lead to some dumb games..."
"Oh, okay, I get it, so your deck can't be very good because you have to play all creatures, and you can't pump it up with enchantments or combat tricks. I guess this could be interesting if there are enough creatures with text that you can actually play an interactive all creature deck."
"Oooh, okay, so it doesn't really have hexproof, and it just makes your stuff more expensive…"
"Oh, but if you do try to play a trick or something, your opponent can kill it at normal rate, okay.."
Where Ari seems to have found Nullhide Ferox clunky and inelegant, I think it's an interesting card with a lot to unpack, and, while it does have a lot of separate lines of text, I think they all make sense together.
Ari disagrees, arguing that this card already has so many distinct abilities that maybe it shouldn't be the card to have extra text about being discarded, but this isn't just a cluster of random abilities; notice that as I read the card, each ability changed the context, meaning, and implications of the previous ability. This is a single concept spread over several lines of text. Now, I'll agree that the discard clause isn't exactly part of the story, but if you think of the first three lines as all being a single ability, which is essentially what's going on here, then we have a card that taxes removal attached to discard hate, which, of course, makes sense, since these are both anti-black, or perhaps in context, anti-Grixis abilities.
