If I play Convergent Mutation targeting a unit to match another unit's might, and one of those units is Ravenbloom Student, what is the final might of each unit?

Ruling: When Convergent Mutation resolves, the targeted unit's might is set to match the reference unit's current might. After the spell fully resolves, Ravenbloom Student's "When you play a spell" trigger is added to the chain and then resolves, granting Ravenbloom +1 might.

Sequence:

• Convergent Mutation resolves completely, setting the targeted unit's might to match the reference unit
• Ravenbloom Student's trigger is added to the chain (since a spell was played)
• Ravenbloom Student's trigger resolves, giving it +1 might

Nuances:

• If Tideturner (2 might) is targeted to match Ravenbloom Student (4 might), Tideturner becomes 4 might, then Ravenbloom triggers to become 5 might
• If Ravenbloom Student is targeted to match Tideturner (2 might), Ravenbloom becomes 2 might, then its trigger resolves to make it 3 might
• Triggers that care about "playing a spell" only activate after the spell has completely resolved
