When two Dazzling Aurora triggers resolve, what is the correct sequence for playing units and resolving their When You Play Me (WYPM) triggers, and can a showdown start while there is still a chain?

Ruling: A showdown cannot start while the game state is closed (i.e., there is a chain). The first Aurora resolves completely, then the second Aurora resolves along with any WYPM triggers from the second unit, then once the state opens, the showdown stages and begins.

Sequence:

• First Aurora trigger resolves: first unit (Deadbloom) is revealed and played
• Second Aurora trigger resolves: second unit (Whiteflame) is revealed and played
• Whiteflame's WYPM trigger goes on the chain above the remaining effects and resolves (can target Deadbloom)
• Once all chain effects resolve and the state opens, the showdown stages
• Showdown begins

Nuances:

• You cannot selectively delay a WYPM trigger - it happens immediately when the unit enters play
• If Whiteflame is played first from Aurora, its WYPM trigger goes on the chain above the second Aurora trigger and resolves before the second Aurora reveals its unit
• The WYPM trigger from the first unit played cannot target a unit from the second Aurora that hasn't been played yet
