When two Dazzling Auroras are in play and the first triggers to play a Deadbloom Predator to an occupied battlefield, does the second Aurora trigger resolve before the showdown combat begins?

Ruling: The second Aurora trigger must resolve before combat can begin. All triggers on the chain must resolve during cleanup before a showdown combat can start.

Sequence:

• First Aurora trigger resolves, putting Deadbloom Predator on the chain
• Second Aurora trigger is still on the chain, preventing combat from starting
• Second Aurora trigger resolves (e.g., hitting another card like Snapvine)
• Any new triggers from that card (like Snapvine's WYPM) are added to the chain and must resolve
• Only after the chain is completely empty during cleanup will combat begin

Nuances:

• If the second Aurora hits another Deadbloom Predator, both can be played to the same battlefield and attack together (they don't enter simultaneously but combat doesn't start until the chain is empty)
• Combat cannot begin while any triggers are pending on the chain
