Scouring Swarm

In the unusual case where Scouring Swarm becomes a copy of something else while its triggered ability is on the stack but before it resolves and seven or more land cards are in your graveyard when the ability resolves, the token will enter as a copy of whatever Scouring Swarm is copying. (Swarms come in many forms.)

Scouring Swarm’s last ability counts the number of land cards in your graveyard as it resolves. This will usually include the land you sacrificed.

If Scouring Swarm leaves the battlefield before its triggered ability resolves and seven or more land cards are in your graveyard when the ability resolves, the token will still enter as a copy of Scouring Swarm, using Scouring Swarm’s copiable values from when it was last on the battlefield.
