Forum:Lightning Chidori Effect.

Hi, guys im new to the forum. I was wondering about the card Lightning chidori.

"When this card is Xyz Summoned: Target 1 Set card your opponent controls; return that target to the bottom of the Deck."

Is that a compulsory effect in order to summon it? or can i get away with not returning a set card? Any input would be appreciated, thanks. :)IppenShindeMiru (talk • contribs) 02:31, July 7, 2014 (UTC)
