Tarmogoyf

Creature - Lhurgoyf X/1+X, 1G (2)
Tarmogoyf's power is equal to the number of card types among cards in all graveyards and its toughness is equal to that number plus 1. (The card types are artifact, creature, enchantment, instant, land, planeswalker, sorcery, and tribal.)

Gatherer Card Rulings [Nov 2009]

• 5/1/2007: Tarmogoyf counts card types, not cards. If the only card in all graveyards is a single artifact creature, Tarmogoyf will be 2/3. If the only cards in all graveyards are ten artifact creatures, Tarmogoyf will still be 2/3.
