Submerge, Waterbound Whenever another unit enters or moves between sites in this body of water, Giant Shark moves to that unit to fight it.
Will it fight units that are Airborne or Stealthed?
Yes. This isn't an attack (which has targeting restrictions), but actually a fight (which simply specifies who fights based on card text).
What path can I choose when resolving this ability?
See Moving to a Specific Location Via a Special Ability or Magic in the Codex.
Will it fight your own units?
Yes.
Does 'enters' include minions that are summoned?
Yes.
If a unit moves within the same site (e.g. surface to underwater, or underwater to surface), does Shark trigger?
No, since the unit is not entering or moving between different sites.
What happens if I summon my minion with Genesis into my opponent's Shark's body of water?
If a Shark moves through a Silence aura, what happens?
The movement and fight still occur. The specific resolution is: Unit enters the water site, Shark's ability triggers. You specify the movement steps to reach the target, and they all go on the Storyline. Shark starts moving. It enters the Silence aura, but the effects of the ability are still on the Storyline and aren't removed, so they continue resolving normally.
