One ruling from Wizards of the Coast
- 1 October 2009While Anthroplasm does become 0/0 for a moment while its ability resolves, state-based actions are not checked until the ability has finished resolving. By that time, it will have some +1/+1 counters on it (assuming X was greater than 0), and so will not be put into its owner’s graveyard.
