Once per turn, during either player's turn: You can pay 2000 Life Points, then target 1 card on the field; destroy that target.

This should be a lot more interesting now that Life Points are becoming relevant. But anyway, this works during both player's turns, which allow for this to constantly mess up your opponent's setup at the cost of a ton of your Life Points. On YCM, people suggested to lower the cost to 1500, but I don't really trust them enough to take their word for it.

I can't really say weather or not this is correct, but I think (or rather hope) it should be near the solution. 

function c70193085.initial_effect(c)
local e1=Effect.CreateEffect(c)
e1:SetDescription(aux.Stringid(70193085,0))
e1:SetCategory(CATEGORY_DESTROY)
e1:SetProperty(EFFECT_FLAG_CARD_TARGET)
e1:SetType(EFFECT_TYPE_QUICK_O)
e1:SetCode(EVENT_FREE_CHAIN)
e1:SetRange(LOCATION_MZONE)
e1:SetCountLimit(1)
e1:SetCost(c70193085.cost)
e1:SetTarget(c70193085.target)
e1:SetOperation(c70193085.operation)
e1:SetReset(RESET_EVENT+0x1ff0000)
c:RegisterEffect(e1)
end
function c70193085.cost(e,tp,eg,ep,ev,re,r,rp,chk)
if chk==0 then return not e:GetHandler():IsDisabled() and Duel.CheckLPCost(tp,2000) end
Duel.PayLPCost(tp,2000)
end
function c70193085.target(e,tp,eg,ep,ev,re,r,rp,chk,chkc)
if chkc then return chkc:IsLocation(LOCATION_MZONE) and chkc:IsDestructable() end
if chk==0 then return Duel.IsExistingTarget(Card.IsDestructable,tp,LOCATION_MZONE,LOCATION_MZONE,1,nil) end
Duel.Hint(HINT_SELECTMSG,tp,HINTMSG_DESTROY)
local g=Duel.SelectTarget(tp,Card.IsDestructable,tp,LOCATION_MZONE,LOCATION_MZONE,1,1,nil)
Duel.SetOperationInfo(0,CATEGORY_DESTROY,g,g:GetCount(),0,0)
end
function c70193085.operation(e,tp,eg,ep,ev,re,r,rp)
local tc=Duel.GetFirstTarget()
if tc:IsRelateToEffect(e) then
Duel.Destroy(tc,REASON_EFFECT)
end
end

Of course, I could also be entirely wrong...

I really like your card, though. Not only because I like Fiend/LIGHT cards, but also because you can kill anything as long as you can pay LP. So yeah, finally a reason besides the wyrm to gain LP^^

Well, thanks about the code, although I honestly am just totally lost about this Mackpro program. Mind helping me get acquainted to it, since I can't figure this out on my own?

Well, I'm still a learner, but I'll do what I can^^
