Is something wrong with the effect? It wont give me the option to xyz rank 5 even though it should. Am I reading something wrong?

If this card is used for an Xyz Summon, you can treat it as a Level 5 monster. An Xyz Monster that was Summoned using this card as Xyz Material gains this effect.
● When it is Xyz Summoned: Draw 1 card.

is this on percy or launcher?

the launcher

might be a prblem with the launcher scripts as i know it works on percy
