Sever the Bloodline

Unless a token is a copy of another permanent or was explicitly given a name by the effect that created it, its name is the subtypes it was given when it was created plus the word “Token.” For example, if an effect creates a 1/1 Soldier creature token, that token is named “Soldier Token.”

If the target creature is an illegal target by the time Sever the Bloodline tries to resolve, the spell won’t resolve. You won’t exile any creatures at all.

Sever the Bloodline has only one target. Other creatures with the same name will be exiled even if they have hexproof or protection.
