It must have been discussed somewhere but I can't find it.

Cinsider I play a Game of cyvasse facing Eddard KL.

Game of cyvasse: Challenges: Each player must choose and kneel a character with an INT icon he or she controls,if able. Then,the player who knelt the character with the highest STR may choose and return a character to its owner's hand.

Eddard KL: Response: Cancel a triggered effect that chooses a character as the only target. Then,draw a card. (Limit once per phase.)

My opponent says he cannot cancel the 1st part of GoC text because it is a cost for playing it. So he kneels a character with an INT icon.

I win the GoC by kneeling a stronger INT character

Know he says he can cancel the 2nd part of my event with Eddard arguing it's a trigger effect that choose a character. So I am not able to trigger the return to hand part of the event (which is the most attractive part) ><

That is the point where i'm a little confused because to me the then part of the event is not triggered ( even if it chooses a character)

Is my opponent right. Can Eddard cancel the whole Game of cyvasse, only the second part ?

It must be obvious, but it is still confusing me. thank you in advance

K.

BTW, I tryed to return to hand a noble crested character, it makes sense.

The first part of GoCyvasse is not a cost. It is a part of the card's effect.

The first part of GoCyvasse targets more than character; so it wouldn't work at the start.

You cannot cancel just one part of an effect. You either cancel all of it, or none of it. So, you cannot cancel just the "post-then" part of an effect; you have to cancel the "pre-then" part as well because they share the same original initiation.

As sWhiteboy says, the characters chosen for the "choose and kneel" part of GoC are not knelt as cost - they are knelt as effects. Remember, costs are the X part of "do X to do Y." GoC's "choose and kneel" is simply "do Y." There are no costs. That means those knelt characters are targets of the effect.

The "choose and kneel" and the "choose and return" parts of GoC are all part of a single effect. Since Eddard says he can only cancel effects that choose a Noble character as the only target of an effect, and GoC has more than one target (all the characters chosen to kneel plus the character chosen to return), Eddard's play restrictions are not met and he cannot cancel any part of GoC.
