Abandoned Hall

Q. I play Sprite Call to create a Sprite token in Abandoned Hall. Does it get +1 might ?

A. Yes.

During the resolution of an effect (in this case, sprite call), new items cannot go past step 1 of the Process of Play (354.3. ). This means those new items will linger on the chain as pending until they are allowed to be processed. This means, until sprite call goes to the trash, the Sprite Token will actually still be pending on the chain.

As we said before, when sprite call finishes resolving, Abandoned Hall will trigger, and (assuming Nern chooses to) will also be placed on the chain as pending.

Pending Items are unique in riftbound as they are processed in the order they were added to the chain, rather than in inverse order, like finalized items are (337.1.b.). This means that the Sprite Token will be processed first, going through the steps of play by being Finalized and then immediately Resolving as it is a permanent (337.1.c.) -- and now we're at full circle! When Abandoned Hall goes to finalize, the Sprite Token will be a valid choice for its target.

Q: Player A has a unit (A) on Abandoned Hall. They play Ride the Wind, targeting unit A and declaring another battlefield as the move destination. When Ride the Wind resolves, may I choose to target unit A with Abandoned Hall’s triggered effect and give it +1?

A: No. Abandoned Hall’s trigger condition is met when a spell resolves. Ride the Wind resolves moving unit A from Abandoned Hall, then leaves the chain, while Abandoned Hall’s trigger is added on the chain as a pending item. When the battlefield’s trigger is being finalized, unit A does not constitute a legal target; if there aren’t legal targets at the battlefield at all, the ability is removed from the chain and it is not finalized. The same process happens when Ride The Wind moves a unit to Abandoned Hall, but in this scenario the trigger finds that unit as a legal target during finalization.

Abandoned Hall + Ride the Wind breviary (“may I give +1 to the unit I just moved?”):

• Ride TO Abandoned → YES
• Ride FROM Abandoned → NO

Relevant Rules:

• From the Unleashed FAQ, about the meaning of “Play”: The first meaning is, “resolve an item on the chain.” This is the play that appears in trigger conditions, in cards like Darius, Trifarian and Ravenbloom Student.
• 402.3. If there are not enough options to make legal choices for a Triggered Ability that has been put on the chain, remove it from the Chain now. It ceases to be a Pending Item but never becomes a Chain Item.
