How do I know if a drink has shroud?

The only way I can think of would be Animate Object plus some effect that grants shroud.

It might be too early, but would you consider doing a podcast on protection/shroud/hexproof/ward as a bundle to talk about R&D’s evolving uses of “you can’t target this” mechanics and what you feel like you’ve learned from them?

I can add it to the list.

If/when: Shroud gets errata'd to Hexproof to match player intuition and "fix" Lightning Greaves.

If. We stopped making shroud because of player intuition, but I doubt we’ll do functional errata.

When we see an evergreen keyword stop being printed, we normally have a replacement (hexproof instead of shroud) or at least something that fills the gap (menace giving evasion to black/red instead of fear, activated indestructible for regeneration). Would you ever just remove something evergreen? Like, something that isn't worth doing anymore, without need for a replacement.

We have in the past. Banding went away and nothing like it became evergreen. I think us doing something today is a little less likely, but not impossible.

Would Wizards consider printing a new card with shroud in a supplemental set?

Maybe in a Modern Horizons set where it’s making a particular reference or it’s important to the design that you can’t target it. Most places we’d use shroud, we’d preferably use hexproof.

"This spell can’t be the target of spells or abilities”. "That’s shroud." Would the rules support an instant or sorcery having shroud on the stack?

I believe so. We’re more likely to use hexproof than shroud though.

Why is Unblockable not a keyword? You can spell out when it's different, like can't be blocked by green, or artifacts, or tokens. Unblockable itself is very concise and easy to understand, it can't be blocked

We tried keyword it it back in Future Sight when we keyworded deathtouch, lifelink, reach, and shroud, but the wording for it wasn’t exact enough to work as a keyword.

A friend is unhappy that Comet's damage ability can get through hexproof and shroud so I'm curious how do you feel about "targeted" removal that doesn't actually target?

Sometimes, you have to do quirky things to make the card work. I do think, as a default, “targeted” removal should target. Here’s my flavor take. “No Comet, don’t attack the creature with hexproof! Comet, stop! Comet! Bad boy!” : )

In regards to Instants and Sorceries with Ward/Hexproof/Shroud: A big part of the problem with creating them is that we already have a definition for what those abilities do while the spell is on the stack, which is nothing. Otherwise, every hexproof creature would be untargetable by counterspells, and so on and so forth. So I'd assume a large part of why it hasn't been utilized is that you'd have to either rewrite the rules to give it a different definition on instants and sorceries, rewrite the abilities to always apply on the stack and change a lot of interactions, or spell it out/create a new ability.

Yeah, I don’t know the rules crunchiness of the issue.

I know that "Can't be countered" has the exact same effect nine times out of ten, but purely hypothetically: Would hexproof/shroud on a nonpermanent do anything?

Stops spell redirection, I guess.
