I think making Red-Eyes available for everyone was not a good thing. Just like now with the Cyber Angels. Within a week everyone and their 10 year old cousin is playing the same damn deck. What a bore. this is just a game. The fun comes when you play 10 different duels against 10 different decks, and have 10 decks of your own that are competitive.
Call of the Mummy definitely has potential to be a meta card, and Ryu-Kokki is decent enough (especially if we get Pyramid Turtle at some point). Monster Rebone might have some utility at some point too. Great rewards? No, but I wouldn't call them "trash" either.
