Spell Effect: Once per turn, if a Spellcaster-Type monster you control would be destroyed: You can pay 800 LP; it is not destroyed.
Monster Effect: When this card battles an opponent's monster with a higher ATK, it gains ATK equal to that monster's Level/Rank x 100 points during the Damage Step only. Once per turn: You can return 2 Spellcaster-Type monsters in your hand to the bottom of your Deck: Target 1 card on the field and destroy it.
Basically, a Pendulum Monster for Spellcasters that's intended to deal with backrow/other troublesome cards + provide some degree of protection from destruction.
Effect is very similar to Snipe Hunter (which I believe is still on the list), so need to make sure that Decks can't abuse it; hence shuffling monsters in the Deck. I could probably have left it at 1 card so you can maintain hand advantage, but need to keep in mind about Shaddolls and how much they like to recycle cards (though the monster thing is prevalent mainly with Hedgehog and stuff).
In terms of its first effect, basically there to help it run over larger monsters; although much bigger ones can still kill it; even with the added power.
Even so, you could just blow up said larger monster with its secondary effect; assuming you have monsters to shuffle back into the Deck.
Pendulum effect protects things from Exciton, Torrential, battle/effect destruction and the like. Also blocks Bottomless to an extent if you need to.
Picture is from Kyng's gallery (the Sentai one) if you need to find it.
Anyway, please CnC.
