Does Riftbound have an 'intervening if' rule, and does Dune Drake trigger on attack regardless of conditions?

Ruling: Riftbound does not have an "intervening if" rule. Dune Drake triggers on attack no matter what, functioning like a conditional ASSAULT 2.

Nuances:

• Even if Riftbound had Magic's "intervening if" rule, Dune Drake's ability wouldn't qualify as one because the condition is not intervening between the trigger condition and the effect.
