Mandrel, Idiotic Linker Frog

Menace
Whenever Mandrel does combat damage to an
opponent, each opponent mills X cards where
X is the combat damage done by Mandrel.
Choose 2 nonland permanents milled this way.
Create an artifact Frog creature token that
enters the battlefield as a copy of one of those
cards with a number of additional +1/+1
counters on it equal to the power of the other.
