Do triggered abilities with 'may' go on the chain even if you choose not to do the effect?

Ruling: Triggered abilities go on the chain regardless of whether you choose to do the effect. When the trigger resolves, you then choose whether or not to do the effect.

Nuances:

• All triggers go on the chain no matter what in Riftbound
• This applies to cards with optional effects ("may") like Flame Chompers, Immortal Phoenix, and Weaponmaster abilities
