MAGIC: THE GATHERING
|Type:||Creature - Spirit|
Stormbound Geist can block only creatures with flying.
Undying (When this creature dies, if it had no +1/+1 counters on it, return it to the battlefield under its owner's control with a +1/+1 counter on it.)
While a decently strong creature mechanic, Undying never really found a home outside of Standard - but it's thriving in Pauper. Stormbound Geist is a Blue sideboard staple, providing a good blocker against creature-heavy aggro decks.
