Collectible Card Game Headquarters

Describe the Bug:
When I enchant a creature the AI controls with Curiosity and that creature deals damage to me, be it combat or noncombat damage, I may draw a card.

I've also tested this with Snake Umbra which produced the same result, so I'm guessing it applies to other, similiar cards, too.

Which card did behave improperly ?
Curiosity

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
BotG v2, duel

What exactly should be the correct behavior/interaction ?
Curiosity controlled by the player only triggers when enchanted creature deals damage to the AI and vice versa.

Are any other cards possibly affected by this bug ?
Probably the following:
Keen Sense (untested)
Helm of the Ghastlord (untested)
Sleeper's Robe (untested)
Sigil of Sleep - tested: when enchanting AI's creature, player can target AI's creatures with Sigil when enchanted creature deals damage to player
Hunter's Prowess + Hypersonic Dragon - tested: when player targets AI's creature with Prowess on AI's turn, player may draw cards equal to damage dealt by that creature to player

Edit1: confirmed by BAgate; Edit2: changed thread title to match new report guidelines

Relevant ruling: " If put on your opponent's creature, you do not draw a card when that creature damages you. The creature has to damage your opponent in order to have this work."

There was a global bug, I fixed it in 7abf526
That goes for Curiosity / Keen Senses (share the same code), Helm of the Ghastlord, Sleeper's Robe and Snake Umbra.
Also code redone for Sigil of Sleep in 67ace90
Hunter's Prowess doesn't seems to belong to this category as it says "player" instead of "opponent"

At least with Curiosity, if you enchant AI's creature and it damages you, Curiosity still triggers and you may draw a card.

Fixed and tested in 0d76c11
