Can I flash mutate extra abilities onto a backup creature?

Asked by Yesterday 1 year ago

Question about the as-of-yet unreleased ability backup, as seen on Boon-Bringer Valkyrie.

In response to my Valkyrie's backup ability triggering, I choose to cast a Sea-Dasher Octopus targeting the the Valkyrie. I put the backup counters on Yargle, Glutton of Urborg. Does Yargle also gain the Octopus's abilities?

Alternatively, I cast Boon-Bringer Valkyrie and, in response to its backup trigger, I flash in an Exchange of Words. When it enters, I exchange the Valkyrie's text box with, IDK, a Swarm of Locus. I backup on Yargle again, because he's a good boy. Does he get the Swarm's ability instead?

And finally, and most importantly, I reanimate both the Valkyrie and Forge, Neverwinter Charlatan with Grusilda, Monster Masher, and the entering creature's backup triggers. Obviously I choose best boy. Does goodest boy ever get the abilities of both cards?

In the interest of everyone's patience, I've also bugged MaRo about that last question. Will post the answer here if/when I get one.

Oh. Allegedly no to all. :(

I'll update this post-release if the notes disagree.
