Need help wording a card effect that is similar but not the same as cards like star drawing

[I Hate Snatch Steal]

Star Drawing, for reference:

http://yugioh.wikia.com/wiki/Star_Drawing

 

The effect is a similar concept but some mechanics of it differ. Lets call the card that has this effect "Card ABC".

 

If an xyz monster is special summoned while it has Card ABC as a material it gains this effect "When it inflicts battle damage, draw 1 card."

 

Same as star drawing, the effect is treated as being the xyz monster's effect.

 

Gaining the effect does not start a chain when the xyz monster is special summoned, but the gained effect will start a chain when the xyz monster inflicts battle damage.

 

The draw effect applies even if Card ABC is later detached, as long as it was attached at time of special summon.

 

The mechanic differences from a card like star drawing are as follows:

 

1. If Card ABC is used as a material to xyz summon Number 39: Utopia, and that number 39 is used to summon number S39 utopia the lightning while Card ABC is still attached, S39 will make you draw when it inflicts battle damage.

 

2. If Card ABC is used as a material to xyz summon Number 39: Utopia, and Rank-Up-Magic Astral Force is used on that Number 39: Utopia to summon number 39: Utopia Beyond while Card ABC is still attached, Beyond will make you draw when it inflicts battle damage.

 

3. If 2.. happens and then Utopia beyond is used with astral force to summon divine dragon knight felgrand while Card ABC is still attached, felgrand will make you draw when it inflicts battle damage.

 

4. Even if a monster has multiple Card ABCs attached at time of special summon, that monster only gains the effect once. EG, using 2 card ABCs to summon number 39 will not let you draw twice when it inflicts battle damage, you will only draw once.

 

Any further questions?

 

If not,

 

Any suggestions on wording?

Hmm, to simulate such effect, I decided to go for the following text:

 

An Xyz Monster that was Summoned with this card attached to it as an Xyz Material gains this effect.

 

The main difference and key part on the effect is on bold.

My logic here is that Star Drawing clauses, reading as "using this card as an Xyz Material", bind the effect to only be applied when directly using the monster as Xyz Material for an standard Xyz Summon.

On the other hand, the suggested "with this card attached to it" clause should allow the Xyz Monster to gain the effect regardless of the summoning method (RUM, card effect, Xyz evolution, etc.), as long as it has that card attached to it at the time it is successfully Summoned. Also I consider important to add that the suggested effect shouldn't apply specifically on Xyz Summons, but on the other kinds of Summons as well (e.g. Flip Summon, Special Summons that aren't treated as Xyz Summons, or in other words, when the Xyz Monster isn't properly Special Summoned). If you don't want this last perk, simply specify on the card text for the effect to apply when the monster is specifically Xyz Summoned.

 

Now then, for binding the effect to be gained only once by the monster, I suppose you could go for a clause similar to the ones used for extra Normal Summons (e.g. Tensu, Pollux)

(This effect can only be gained by that monster once.)

 

So, in the end, it should look like this:

An Xyz Monster that was Summoned with this card attached to it as an Xyz Material gains this effect. (This effect can only be gained by that monster once.)

Simple.

 

While this card is attached to an Xyz Monster as Xyz Material, that monster gains this effect.

-When it inflicts battle damage to your opponent: You can draw 1 card. 

You can only use this effect of "ABC Card" once per turn.

Simple.

 

While this card is attached to an Xyz Monster as Xyz Material, that monster gains this effect.

-When it inflicts battle damage to your opponent: You can draw 1 card. 

You can only use this effect of "ABC Card" once per turn.

 

No effect is used, as that is a continuous effect, and the OPT doesn't do anything.

 

Darj's OCG seems fine.
