Building a deck around Rionya doing extra combats through schenanigans involving copying creatures that cause additional combats on attack.

My question is in regards to [[Desert Were-Worm]]'s wording of "Whenever you attack with creatures with total power 12 or greater for the FIRST time each turn, untap all attacking creatures. After this phase, there is an additional combat phase."

Does [[Desert Were-Worm]] only consider the first combat phase since [[Desert Were-Worm]] entered for its ability or would it not synergize properly because it considers ALL combats even before it enters in a similar manner to cards that specify "Second card drawn" or "Second spell cast" like [[Alisaie Leveilleur]] or [[Atlantean Cavalry]]

Am currently designing a Mairsil deck and there are a few self referential cards relating specifically to cards exiled by them, ala [Imprint].

I have 2 questions in specific:

1 - Do viable imprint cards still work properly on Mairsil? As in, "Do ALL cards exiled via Mairsil count towards [Imprint] for any activated abilities that would require an [Imprint] interaction?"

2 - Would the activated ability of [Valki, God of Lies] allow you to turn Mairsil into a copy of any card exiled by Mairsil or is it a dud?

Building a commander deck that could potentially use Jace Reawakened in the 99 alongside Mirror Room//Fractured Realm and noticed something that I am most likely misinterpereting or just don't know enough about how it works to confidently play it out in a game. I have also not seen a particular Ruling to note any clarifications.

​

The problem is Jace's secondary +1 being "You may exile a card with mana value 3 or less from your hand. If you do, it becomes plotted."

​

For the rulings, my questions are 2:

- Is Mirror Room a valid target, being a 3 mana value spell, or does the FULL(or even highest) conjoined mana value of Mirror Room//Fractured Realm count? This would also be a significant ruling for other split cards in relation to things like Sin Prodder, Dark Confidant, and such when determining outcomes... is it a "choose the better option for you" or is there a set result?

- If it is a valid target to become plotted, can out cast Fractured Realm via the card itself being Plotted or does the option to cast Fractured Realm at all become manual cast or no cast at all(unless you have other methods to cast from exile)?
