Patchwork Automaton [The List]

Ward {2} (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays {2}.)
Whenever you cast an artifact spell, put a +1/+1 counter on Patchwork Automaton. It dwells happily near the ever-burning forges of Sokenzan City, crafting small things of beauty from discarded scraps.
