Carlvelt, Hexstar Trap

Partner
Trample, First Strike
Carlvelt, Hexstar Trap's power is equal to the number of nontoken Artifacts on the battlefield. This checks after every end step.

Ironcharger—When this creature deals combat damage to a creature with higher toughness than itself, it deals 2 extra combat damage to that creature.

Essentially a mechanical version of a near extinct trap Bakugan, it still manages to be more attack oriented than anticipated.
