What's that, you stole my 4500 ATK monster and paid 4500 LP? Dark Hole. Dimensional Prison. Et cetera.
By using this card you're relying on your opponent to have a worthwhile monster to steal. Furthermore the LP cost is punishing and can cause conflicts with the Solemn brigade. A simple monster removal card could in effect cost you anywhere between 25% and 50% of your original LP.
If you're looking for a lulzy trap that isn't staple, it's worth looking else where. Side deck material for rogue decks at best.
