I am pretty sure this is what happened, although maybe I missed something.
1. The priest played a Lightspawn.
2. Lightspawn is now a 5-5
3. I silenced the Lightspawn with Keeper of the Grove
4. Lightspawn is now a 0-5 .
5. I hit it with a 1-1
6. Lightspawn is now a 0-4
7. Priest heals the Lightspawn to (0-5) (I laughed) and then used two Divine Spirit spells, buffing it to a 10 attack (I cried)
I was taken by surprise because I considered the silenced (0-5) Lightspawn castrated.
Question: If the Lightspawn is silenced shouldn't its Attack = Health trait be nullified?
