While you have a "Ki-sikil" monster in your GY and you have a "Lil-la" monster in your GY, this card gains 2200 ATK/DEF
With a market price of $32.53, thats not bad at all for an Illustration Rare-tier card
If you changed it to a card that you control, then it would be more balanced (similar to the anime version of Guardian Dreadscythe).
