My 48 hour impression

Lol yeah I have seal card overload now too. I had to waste a bunch this morning so they didn't take 2 backpack slots.

There also is no way to increase the ranking of monsters like the Draconus (sp?) and Twiggy/Branchy and Neo and Poe that you can only ever get one of.

Is there really no chance of getting another Twiggy? Mine has such a bad ranking..

The thing about seal cards...
At 1st it seems like you can't keep enough. There's always always a new monster to catch. But then you get to sealed space, its been a long journey and you've been hunting and catching all these monsters like the tasks ask you to. And then you run out of new monsters to catch. You've been hoarding seal cards, they're so handy and you need them. Now you have over 50 and your on your second slot of them.
At this point you need to be VIP 4. If you don't plan on spending real money just start selling your cards off. At VIP 4 you can bless your monsters breeding and get the slightest of boosts to your new monster, but to fill up your blessing you need to catch monsters to sacrifice. Without a boost if you breed 2 Cs you should get a C+. With a boost you should get a B-
This has been my experience. If you have differing opinions I'd love to hear them.
