I tried doing so by using the IsExists function but I don't know how to fill in the Parameters, resulting in the error message:"Parameter 4 should be "Card"." In the following spoiler i'll highlight the corresponding line and hope that I get help soon. Thanks in advance. function c161182004.operation(e,tp,eg,ep,ev,re,r,rp) if not Duel.IsPlayerCanDiscardDeck(tp,3) then return end Duel.ConfirmDecktop(tp,3) local g=Duel.GetDecktopGroup(tp,3) if g:GetCount()>0 then Duel.DisableShuffleCheck() if g:IsExists(c161182004.filter,1,nil) then Duel.Hint(HINT_SELECTMSG,tp,HINTMSG_ATOHAND) local sg=g:FilterSelect(tp,c161182004.filter,1,1,nil) Duel.SendtoHand(sg,nil,REASON_EFFECT) Duel.ConfirmCards(1-tp,sg) Duel.ShuffleHand(tp) g:Sub(sg) Duel.SendtoGrave(g,REASON_EFFECT+REASON_REVEAL) local h=Duel.GetMatchingGroup(c161182004.spfilter,tp,LOCATION_HAND,0,nil,e,tp) if sg:IsExists(c161182004.spfilter,1,1,sg) then if Duel.GetLocationCount(tp,LOCATION_MZONE)<=0 then return end if h:GetCount()>0 and Duel.SelectYesNo(tp,aux.Stringid(161182004,2)) then Duel.BreakEffect() Duel.Hint(HINT_SELECTMSG,tp,HINTMSG_SPSUMMON) local sc=h:Select(tp,1,1,nil) Duel.SpecialSummon(sc,0,tp,tp,false,false,POS_FACEUP) end end end end end Edited by user Wednesday, January 11, 2017 8:51:57 PM(UTC) \| Reason: Not specified

That will be done for all cards in your "sg" group. If the number of trues your c161182004.spfilter returns, is equal to or greater than 1 (in this case), it will finally return true.
