Perhaps Im just having my own Old Man Yells at Cloud moment here, but it lends a sort of annoying inconsistency to your decks and the board state that might be funny at first glance but becomes rather grating over time

Add another 4 floors full of pokmon goodies, buying stations, and a tournament area, and youve got Hareruya2, the 6-floor behemoth located just seconds away from the station
An Abyssal Specter may not get played because every deck can block it
An opponent not crippled by this card was either way ahead on the board or had already lost
This type of card is usually used by adding one copy to an aggro deck in Limited, but if you have a villain deck, it might be fine even in a slower deck if you can get two turns out of it
