I don’t think Dynamic Duo knows that Amalgadon is a Quillboar.
My composition was golden Dynamic Duo, Amalgadon, Tough Tusk, golden Agamaggan, 2x Charlga, Golden Charlga.
I would have expected the Duo to get +52/+52 per round. (Charglas put 4x blood gems on 5 different quillboars for 20 total gems. Golden Duo gets +40/+40. Charglas put 4x gems on the Duo itself, each worth +3/+3. Golden Duo gets +12/+12, total +52/+52.) Instead, it was getting +44/+44. My only guess was that it didn’t think the Amalgadon was a Quillboar.
