Sever the Bloodline

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

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.

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 a card with flashback is put into your graveyard during your turn, you can cast it if it's legal to do so before any other player can take any actions.

To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.
