This card cannot be Special Summoned. This card returns to its owner's hand during the End Phase of the turn it is Normal Summoned or flipped face-up. When this card inflicts Battle Damage to your opponent, draw cards until you have 5 cards in your hand.

So here's a thought....
This is searchable by Aratama, Blaster, etc.
This is playable through Stormforth, Nikitama, and whatever the hell you can come up with to get it to the field, which is absurdly easy to accomplish.
Dealing damage with this card lets you draw until you have 5; Pulling this off is ridiculous by itself, as you draw anywhere between 0-5 cards, and on average, you draw like, what, 2-3? That's still pretty cool.
HOWEVER....
It's a Spirit monster.

I remember people teching this in Qliphort, at least before the ruling was official on whether the summon effects were in fact effects.
