If I control two copies of Allay, Eager Admirer at the same battlefield, do my other units there have Deflect 2?

Ruling: Yes. Each Allay, Eager Admirer grants Deflect (which defaults to Deflect 1) to your other units at that battlefield. Since Deflect values from multiple sources are summed, your other units will have Deflect 2.

Nuances:

• Each Allay will also have Deflect 2 themselves (their own printed Deflect 1 plus Deflect 1 granted by the other Allay).
• When a Deflect value is omitted from the keyword, it defaults to 1.
