This card can attack your opponent's lifepoints directly. For each time If this card attacks inflicts battle damage to your opponent's lifepoints by a directly attack: This card it gains 1000 ATK. If During the End Phase of the turn where this card where to be was sent to the Graveyard or banished: removed from play, Special Summon it back to the field in face-up Defense Position mode at the end phase of that turn.

So, this is a super version of Raging Flame Sprite that is impossible to get rid of. It doesn't help that its revival effect doesn't specify where it was sent to the Graveyard or banished from, so you could mill it or discard it and it will be back. Bouncing or spinning won't help since it's a no-Tribute non-Nomi monster.

 

Water down its revival effect - at least ensure that it triggers only when this card was sent there from the field. This means that if it was banished from the Graveyard it'd be gone for good, but not if it was banished from the field.
