Tarmogoyf + Seal of Fire

[Citanul]

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.)

sacrifice Seal of Fire: Seal of Fire deals 2 damage to target creature or Player.

Let's say there is only land in the graveyard so Tarmogoyf is a 1/2. Opponents sacrifices Seal of Fire targetting the Tarmogoyf to deal 2 damage. Does the 2 damage resolve before the enchantment hits the graveyard?

[Clariax]

Sacrificing the Seal is the cost of the ability, so the seal will be in the graveyard long before the ability resolves.

[Anusien]

I would point out that State Based Effects are not checked in the middle of resolving a spell.  Therefore, a 1/2 Tarmogoyf (powered by a Creature) targeted by a Shock will grow to 2/3 when the Shock finishes resolving.  Then State-Based Effects will be checked and see a 2/3 Tarmogoyf with 2 points of damage on it.
