I should clarify. It's not that the Wizard would be (more) broken if this were arcane. It's that I'm glad every mage has access to it at no more than 2 spell book points - including the Warlords. It's especially cheap for the Forcemaster (and Siren?), but my Forcemaster might not want it because she often teleports the enemy to her zone.
So... first FAQ question. If a zone has both a face-down Astral Anchor and [mwcard=MW1E38]Teleport Trap[/mwcard], and the Trap gets sprung, can the Astral Anchor be revealed to prevent the Trap from doing anything (and if so, before or after the cost of revealing the Trap is paid)? And similarly, if the Trap is in a different zone and gets sprung, and the Trap's controller tries to teleport the triggering creature to a zone with Astral Anchor face-down, and the Anchor is revealed, does the Trap "fizzle" or can a different (not really "target") zone be chosen as the creature's destination?
(Regarding the latter, I don't think there are any timing windows between steps once the card text is being resolved, so if the Anchor wasn't revealed before resolving the Trap, it's too late and the Anchor won't do anything until after the creature has arrived in the zone)
