Seize the Storm

If you cast Seize the Storm with no instant or sorcery cards in your graveyard and no cards with flashback in exile, the Elemental will start as a 0/0 creature. However, state-based actions won't be checked until after Seize the Storm has finished resolving. The Elemental will then be a 1/1 creature and survive because Seize the Storm will either be in your graveyard or in exile.

While a spell is on the stack, it is neither in your graveyard nor in exile, so it won't contribute to the Elemental's power and toughness. For example, with Seize the Storm in your graveyard and no cards in exile, the 1/1 Elemental in the above scenario will become 0/0 and die if you cast Seize the Storm from your graveyard using flashback.

The power and toughness of the Elemental token will change as the number of instant and sorcery cards in your graveyard and the number of cards with flashback you own in exile change.
