Does Dazzling Aura stack if you have multiple copies?

Ruling: Yes, Dazzling Aura stacks. If you have two Dazzling Auras, both triggered abilities trigger separately at the end of your turn and resolve independently.

Sequence:

• At end of turn, both Dazzling Aura triggers are added to the chain
• Priority passes for reactions
• Resolve the first Dazzling Aura effect (reveal and play a unit)
• Any triggered abilities from the played unit are added to the chain and resolved
• After all new triggers resolve, resolve the second Dazzling Aura effect
• Any new triggered abilities are added and resolved
• Chain closes when all effects are resolved

Nuances:

• Triggered abilities in Riftbound don't need to explicitly say they stack - multiple instances of the same triggered ability trigger separately
• Spirit's Refuge is an exception that "doesn't stack" due to its "if they didn't already" clause
