I want to use its effect more than once per turn but something about: recursive event trigger appears as a script error.
--Activate
local e1=Effect.CreateEffect(c)
e1:SetType(EFFECT_TYPE_ACTIVATE)
e1:SetCode(EVENT_FREE_CHAIN)
c:RegisterEffect(e1)
--coin
local e2=Effect.CreateEffect(c)
e2:SetType(EFFECT_TYPE_FIELD+EFFECT_TYPE_CONTINUOUS)
e2:SetRange(LOCATION_SZONE)
e2:SetCode(EVENT_TOSS_COIN_NEGATE)
e2:SetCondition(c36562627.coincon)
e2:SetOperation(c36562627.coinop)
c:RegisterEffect(e2)
end
function c36562627.coincon(e,tp,eg,ep,ev,re,r,rp)
return ep==tp and Duel.GetFlagEffect(tp,36562627)==0
end
function c36562627.coinop(e,tp,eg,ep,ev,re,r,rp)
if Duel.GetFlagEffect(tp,36562627)~=0 then return end
if Duel.SelectYesNo(tp,aux.Stringid(36562627,0)) then
Duel.Hint(HINT_CARD,0,36562627)
Duel.RegisterFlagEffect(tp,36562627,RESET_PHASE+PHASE_END,0,1)
Duel.TossCoin(tp,ev)
end
end
