This is easily the second most powerful spell in the game (right after Fear), only losing out to it because you don't always have a valid target to switch with (or the spells to do so). This card is not only very strategic, but it is a lot of fun as well. We play with a lot of powerful/overpowered Epic Heroes, so it is always fun to switch those around with each other (even if you're just putting one back in town to deal with later).
