1- Sivvi's Valor doesn't target creature to prevent damage to it so it can be played even if all creatures have shroud.
2- You can't play Sivvi's Valor in advance.
3- Doesn't redirect damage made to any creature to player.You are asked to select target damage card and then nothing happens.Also you are allowed to select damage card of a player.

Sivvi's Valor

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2014/11/14: Khans of Tarkir,duel

What exactly should be the correct behavior/interaction ?
1- Sivvi's Valor targets creature.
2- You can play Sivvi's Valor in advance.
3- Redirects damage made to any target creature to player.You can't select to redirect damage made to a player.

Are any other cards possibly affected by this bug ?
-

This is reminding me of a bug for another card that was fixed, but I can't remember it.

1 and 2 are confirmed.
3 is partly confirmed. It doesn't redirect the damage for which it is applied, but it does redirect any damage done for the rest of the turn.

EDIT: Bug 3 reminded me of Silhouette, see bug here.

All fixed in b4c7c50
And yes, it was similar to the Silhouette bug. I hope AI could understand the new code.
