@Elysiume:

This is rated (somewhat) low because it's a niche card. The problem is that once you're at five mana, accelerating beyond that is rarely a good plan. Yes, you can totally use him to power an epic Drain Life, or as part of an infinite-mana combo or to massively pump your shade or whatever... but all of those rely heavily on other fairly specific cards; you are rarely going to see a deck with a large number of cards that do well with more than five mana.

His 4/4 body, with no other abilities, is a bit below what his cost is worth -- this means that if you draw him and don't immediately have a combo or something to do with the mana he produces, he's a bad card. And it's hard to envision a deck with him where that won't happen fairly often.

As a result, this card is fun for kitchen table combos but not really practical beyond that. Sure, you might remember the time you used him to fuel that epic Drain Life or made your Shade huge or whatever, but I suspect you're ... (see all)
