Arna Kennerüd, Skycaptain

Rulings

A creature that is equipped is considered modified no matter who controls the Equipment that's attached to it. — A creature with a counter on it is considered modified no matter what kind of counter it is or which player put it on that creature. — An Aura controlled by another player does not cause a creature you control to be modified. — If, for any reason, an Aura token that would be created with Arna Kennerüd's last ability can't be attached to the appropriate creature, that token isn't created. If an Equipment token that can't be attached to the appropriate creature would be created, that token enters the battlefield unattached. — To double the number of each kind of counter on a permanent, put another counter on it for each counter it already has. Effects that interact with counters being put onto permanents, such as the effect of Branching Evolution, apply as appropriate.
