The ability that defines Chimney Goyf’s power and toughness works in all zones, not just the battlefield. If Chimney Goyf is in your graveyard, it will count itself.

Chimney Goyf counts card types, not cards. If the only card in all graveyards is a single artifact creature, Chimney Goyf will be 2/3. If the only cards in all graveyards are ten artifact creatures, Chimney Goyf will still be 2/3.

The card types that can normally appear on cards in a graveyard are artifact, creature, enchantment, instant, land, planeswalker, sorcery, and tribal. Legendary, basic, and snow are supertypes, not card types.

Some playtest cards have unusual type lines. To determine whether those cards have a card type not listed above, refer to that card’s Card-Specific Notes in this document.

If an instant or sorcery spell deals damage to Chimney Goyf or lowers its toughness, that spell is put into its owner’s graveyard before state-based actions are performed. If that spell is the first of its type to enter a graveyard, it will raise Chimney Goyf’s toughness before the game checks to see if Chimney Goyf dies.
