When you control multiple Dazzling Aurora permanents, do both triggers resolve before any creatures enter, or does the first creature enter before the second trigger resolves?

Question

Accepted Answer

When you control multiple Dazzling Auroras, each permanent’s “At the end of your turn” Triggered Ability is placed on the chain in the order you choose, and they resolve one at a time. Each trigger that resolves will reveal and instruct you to play the revealed unit; that play becomes a pending play item and is finalized and resolved before the next Dazzling Aurora trigger resolves. In short: a creature enters between the triggers (the first played creature will enter before the next trigger fully resolves).

You put all of your Dazzling Aurora triggers on the chain in the order you choose [383.3.d]. The newest trigger resolves first [340.1]. When that trigger resolves and tells you to play the revealed unit, that Play becomes a pending play which is finalized and resolved before continuing to older chain items [340.3] [355.2] (see the analogous example in the FAQ) [FAQ:unleashed#16]. Therefore the first creature enters before the next Dazzling Aurora trigger resolves.

At the end of your turn, each controlled Dazzling Aurora’s Triggered Ability triggers simultaneously and you choose the order to place those triggers on the chain [383.3.d]. The newest trigger on the chain resolves first (LIFO) [340.1]. As that trigger resolves it reveals from your deck until it finds a unit and instructs you to play that unit. Playing a unit is a play action that becomes a pending item to be finalized/placed on the chain [355.2]. After the trigger creates that pending play, resolution continues, and because there are Pending Items the rules return to Finalize so the pending play is finalized and placed on the chain and will resolve as the newest item [340.3]. The play of that revealed unit therefore resolves (the unit enters) before the next Dazzling Aurora trigger (an older chain item) resolves.

If the first trigger’s reveal cannot find a unit (e.g., no units left in your deck), follow the instructions as much as possible; partial execution rules apply and you simply won’t play a unit in that instance [359.3.e.11]. If some effect modifies or prevents the play of the revealed card when the trigger resolves, the play may become illegal or produce a pending item that later becomes null; the general pending/item resolution process still governs which items resolve first [340.1] [340.3]. If different players controlled different Dazzling Aurora triggers (not the situation you asked about), trigger ordering among players would follow the multi-player ordering rule starting with the turn player [383.3.d.1].

Each Dazzling Aurora’s text is a Triggered Ability that triggers “At the end of your turn…” Multiple such triggers that are triggered simultaneously are ordered onto the chain by the player who controls them [383.3.d]. The chain resolves newest-first, so the last trigger you placed on the chain will resolve before the others [340.1]. When one of those triggers resolves it instructs you to play the revealed unit. Playing a unit is a play action (you make the choices for that play during finalization for the play) and, as shown in similar examples, that play becomes a pending item on the chain while the source ability finishes resolving; because there is a pending item, the game returns to Finalize and that pending play is then finalized/placed on the chain and will resolve as the newest item before the older chain items continue [355.2] [340.3] [FAQ:unleashed#16]. Therefore the unit from the first-resolving Dazzling Aurora will actually enter (the play resolves) before the next Dazzling Aurora trigger resolves. This means creatures will enter between resolutions of multiple Dazzling Aurora triggers rather than all triggers resolving first and then all creatures entering.
