Cost + effect vs cansel

By argyles, in 2. AGoT Rules Discussion

as i was playing with my friends we had an argument about this :

Stark player has a kneeling character and in challenges plays : To be a wolf to stand the character and bring 1 card bla bla bla

opponent player plays : Paper shield .

the arguement is this : Stark player claims that the standing is the cost part of the "to be wolf " card so the character stands and the effect that is canseled is the rest .

the opponent player says : paper shield cansels everything from the beginning .

so the question is : Is the standing part the cost effect of the "to be a wolf" ? so when you cansel the trigger effect of the card the character still stands but no card is searched... or the standing and the searching are 2 effects so when paper shield comes it cansels the first (and therefore the second) so nothing happens ?

plz help .

sorry for my bad english

This is true. The To Be... events are a bit unique in that standing a character is an unusual cost for an effect, but it is indeed the cost. Whenever there's a "Do X to do Y" construction, X is always the cost for the effect. And costs are paid as part of initiating the effect, it's not part of the effect. So cancelling an effect never undoes the payment of the costs. If a card says "kneel a character to do something", and the effect is cancelled, the character remains knelt. Here it's the same, just that the character is stood to pay for the cost.
