Is Blue-Eyes still worth investing in? The structure deck, I mean. I already have three of Silver Cry, three Snipe Hunters, three White Stone of Ancients, three Ebolas - all with a lot of patience - and I don't know if I should spend real money on getting another Cosmo Brain and Dragon Spirit of White? I don't care much about reaching King of Games but I'd like to reach Legend at least + have some fun playing, and Anki is not cutting it anymore. I also have over 9k gems and I'm considering spending them in Black Rose box to get Shrine and Vermillion.
Blue eyes is one of the best decks right now and has been for a very long time. But in order to be competitive you have to buy the structure deck. So it depends on you if you want to spend real money on the game go for it. If not Six Sams and Triaminds are great deck which you can build with gems
