- 1 October 2009A token's owner is the player who created it.
- 19 March 2021A token you own that's returned to your hand moves to your hand before it ceases to exist. This will cause the last ability of Stormfront Riders to trigger.
- 19 March 2021You may return Stormfront Riders itself to its owner's hand as its triggered ability resolves. If you don't control two other creatures, you must return it.
- 19 March 2021The ability of Stormfront Riders doesn't target any creatures. Because of this, no player may take action between the time you choose the creature to return and the time you return it.
- 19 March 2021If Stormfront Riders and another creature are returned to your hand at the same time, its last ability triggers for each of them.
- 19 March 2021If you control only one creature as the triggered ability resolves, you return it to its owner's hand.
