Tachikaze Master: The point being made is not that Ragnarok is bad, but it's not as effective in a competitive environment. If you want to play a fun deck, combo decks are always extremely entertaining. But if you want to be competitive, you have to be able to maximize the consistency and utility of your deck. Because Ragnarok has so many pieces, including the gleipnir set spell, fulfilling your strategy will be very difficult, and will be very much reliant on the cards you draw.

Point being, play it if you want. But if you want to have a discussion about the quality of a card, you'll need to ensure that the scope of the discussion is fully qualified.

As a side note, I wanted to build Ragnarok, too, but I found "Disgard" to be a much more interesting build. And in the end it's the more consistent as it only relies on two pieces: a discarder, and discard fodder.
