When you put this creature into the battle zone, you may unlink a linked God in your battle zone with the names "Zen" and "Aku". If you do, search your deck. You may choose a card from it with the name "Violence Heaven", "God Bringer", or "God Saga". Shuffle your deck. Then, you may cast the chosen card without cost.
Whenever this creature would leave the battle zone, if you have a God in the battle zone, this creature stays in the battle zone instead.
