Dynastic Diadem vs Break Stature

[dusk fox]

Having some trouble coming to a satisfying conclusion on how this interaction works. My first instinct is that you can still choose a fealty token with break stature's effect, the destroy part will fail, and then the rest of the effect will resolve and prevent fealty tokens from being created for a turn. I read the release notes but didn't feel that this clarified enough for me especially since the release notes came out before Diadem. Unsure what the relevant entries in the comprehensive rules would be.

Break Stature is stopping the creation of auras that share the name with the aura token destroyed. As Fealty was not a legal parameter for the destroy effect, Fealty tokens could still be created.

It doesn't say "if you do", it will stop fealties from being created despite not destroying it

[tulip bolt]

I was thinking 1.8.6 would mean you cannot choose Fealty as the aura to be destroyed at all. So if there was a Ponder and a Fealty controlled by Nic, Tyler must choose the Ponder. If there was only a Fealty, they could not choose the Fealty and the destroy effect would fizzle.

CR 1.8.6

1.8.6 If the parameters of an effect are undetermined at the time the effect is generated, the player instructed by the effect determines the parameters of the effect. If no legal parameters exist, then any part of the effect related to those parameters fails.

See examples with </cr_example:1380739510270169141> 1.8.6

1.8.6a If two or more players are instructed to determine the parameters of an effect, those players determine the parameters in clockwise order, starting with the controller of the effect. [1.1.6]

See examples with </cr_example:1380739510270169141> 1.8.6a

But I'm happy to be reading it wrong.

[native hinge]

It is legal to try to destroy something that cannot be destroyed, so I read that as you can decide to try to destroy the aura even if in the end you cannot destroy it

[dusk fox]

Does this mean we don't know what the answer is?

[vernal scroll]

if it came up in an event I would rule that fealties are still prevented from being created

[stone compass]

I don't have a +1 emote but I'd agree with that judgement for Patrick's reasoning, no "If you do" clause on the second part. Contrast with Runic Reclamation.
