First try it out and see if you like it.
But it is closed Alpha, invite only, right now. We may invite more people in a few months. Follow @metarobots if interested in an invite.
And it is not really set up for investing in. You can earn in-game tokens there and use them to buy Battle Card Game packs. You can also buy in-game currency with HBD but you don't have to. We have no requirements for you to buy anything.
Oh wow
Thanks
