Scrap (As an additional cost to play this, you may banish an item or equipment from your graveyard.)
When this attacks, if it scrapped a card, this gets overpower.(This can't be defended by more than 1 action card.)
Crank (As this enters the arena, you may remove a steam counter from it. If you do, gain an action point.)
This enters the arena with 2 steam counters. At the start of your turn, destroy this unless you remove a steam counter from it.
When you boost an attack, destroy this. If you do, the attack gets +X{p}, where X is the number of steam counters on this.
