Repost: Shining Future Magician

[Dasan]

I might make a Support later on so here goes

 

Shining Future Magician

Rank 4

[spellcaster/Xyz/Effect]

ATK/2500 DEF/2100

2 level 4 monsters

Once per turn: you can Detach 1 Xyz Material from this card, then you can target 1 LIGHT monster in your Graveyard; banish it, and if you do, this card gains ATK equal to halve of the banished monster's original ATK until the End phase. During your turn, If this card is in your Graveyard: you can Special Summon this card, then Special Summon 1 LIGHT Xyz monster from your Extra Deck that is 1 rank higher by using this card as an Xyz Material except number monsters. (This is treated as an Xyz Summon.) You can only gain this effect once per duel.

You should make it harder to summon it from the grave,

like banishing a light monster from your grave for example, or even returning one to the grave.

Most cards that special summon themselves from the grave have a condition.
