It makes sense, mainly when the most expensive pokemon card can sell for more than a car
The power of his army will grow over time, eventually flooding the battlefield with hordes of Uruk-hai
Helping sift through your deck for creatures, making them cheaper to play, and being strong enough to be used as an attacker or defender, there's no time during the game where this card isn't going to be of great use
When it's in the Graveyard, you can banish Orcust Crescendo to add a Dark Machine Monster that is either banished or in your deck to your hand
Of course, there are stories of this thing completely changing the game, but in general, there is usually enough enchantment removal floating around that most of the time this will probably do nothing (expect possibly draw out that enchantment removal, but you dont usually want to approach the game like that, especially in multiplayer)
