The past few weeks I've been trying to set myself up for the release of Abyss Rising by learning what the good Mermail and Atlantean cards do. I must admit that Dueling Days' post helped a lot! I've been picking up random stuff like Undines, and even a set of German Super Deep Sea Divas. I got to test with Vampire last night, with basically no idea what I was doing besides reading the aforementioned post. In just an hour I was doing some pretty sick things and had a pretty decent grasp of the deck. I can't wait to see what kind of Water exclusives we get for this archetype to be top tier (hopefully not broken, but top tier) and see what the TCG version of the deck may evolve into.
One thing that I'd like to note though, is that it didn't seem necessarily busted even though the deck does do pretty sick things. Getting a +2 off an Undine summon is pretty sweet. It sort of felt like Inzektors with more search capability, boss monsters, but fewer pops. Like I've mentioned before, decks nowadays need to do at least something busted to be competitive. You can see this with the decline of Heroes; they never really did anything busted even though it's still a good deck.
Testing with this deck is particularly important since ABYR will be legal for YCS Seattle. It makes it less than ideal when there's a product release and then a YCS like a week later. I would expect the field to largely be what it is currently, but it will be annoying having to play against new Prophecy and Madolche cards if you have no idea what they do. Not much you can do besides testing with the good ol' DN I suppose lol.
