Master Moulder

When this spell enters the Battlefield, place 6
Batch counters on it.
{1}: Remove 1 Batch counter from this Artifact,
and place it on a Skaven Creature you control.
Once per Creature, during your Main Phase, you
may pay the Squad cost of a Skaven you control
with a Batch counter on them, and create a
token copy of that Creature.
