Rule 607.3 change

[KitsuLeif]

607.3
Linked abilities can get weird when one of the abilities exiles one card and the other talks about the one exiled card, but through shenanigans like Panharmonicon, we get two exiled cards. The rules around resolving this weirdness were accidentally tripping on their own feet. They said that talking about "a" card saw all of the cards if we were getting information on them or taking actions on them, but that's not true—every ability taking actions on the cards wanted you to pick one. This rule's been updated to say so. Abilities that ask for information about the cards still check both.

Looks like this is the end for Isochron Scepter double casts. Before this change, when you somehow had two spells inside Isochron Scepter you would have either cast both or none. Now you have to decide for none or one to be cast, but you can't cast both anymore.

I am almost positive that does not change. The rule was updated so things like Mimic Vat would work the way it has been ruled to work. That is, only one card is copied. Scepter doesn't say "a" card; it says "the" card. Which is different.

We should wait for the exact wording of the CR to be sure but based on the summary above, I don't think anything that references "the" card will change.

Is it even possible to get multiple creatures under Mimic Vat, when it says, each creature card exiled with it is returned to the graveyard, when another one gets imprinted?

so much for interesting things with banisher priest.

Mutate When a Mutated creature dies, the Vat trigger exiles all the cards that made up the creature on the field. Just like Persist and Undying see the individual cards to bring them back, so too will Vat exile each card as part of the same action so there is no "other card" to return yet.

This rule change has nothing to do with Priest since it doesn't have a linked ability.

Indeed, Iso is untouched. Man, this is confusing.

Only so much as reading a card is normally confusing. People always try to associate things because they feel they are similar. If you read the card and read the rules and don't try to assume that something unsaid is actually said it's fairly cut and dry. It's when you stop and think "But wait, maybe when this says "the card" it means "a card" then that means this is affected!?!" that's when you get confused in the same way people are constantly confused by the word "target" assuming it means "affect". Too many people look at cards and think "This "affects" this card, so that means it "targets" it right?" people get over this eventually but they don't actually get over this assumption they simply create a known exception.
