[confirmed]Giant Shark vs. regeneration

[Korath]

Describe the Bug:
Giant Shark pumps itself only when blocking or blocked by creatures that are currently damaged.

Which card behaved improperly?

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)

What exactly should be the correct behavior/interaction?
Creatures that were damaged this turn, even if they've regenerated since then. (But not if all damage was prevented.)

Are any other cards possibly affected by this bug?
Just about everything that examines card_instance_t::damage_on_card. There might be some effect somewhere that specifically states "Target damaged creature" or similar, but I can't think of one - just about all such effects are templated "creature that was damaged this turn".
