Tinker Tools

Activated abilities of Riggers you control cost {1} less to activate. This effect can't reduce the amount of mana an ability costs to activate to less than one mana.
Tap an untapped Rigger you control: Remove a Contraption card in your graveyard from the game. (It is not exiled, it is no longer a part of your deck.)
Contraption creatures you control get +1/+1.
