Shadowverse

Check this out, it's so cute.
I should really build a Lindworm deck. Although, I couldn't resist and spent some dust on a second Barmic while upgrading my main deck, but whatever.
I should also build a second Loki; I'm cheating with Gamelon when I can, but it's still not the best use for him. And a third Silva, two just isn't enough.
And I need to expand the pool of light creatures for my sword deck; it's not fashionable to run only one Zeta anymore, and many builds have the screaming guy 2.0...
It's good that Blood is weak right now, so I don't have to spend resources on their Furson, and I already got Vira.
But overall, I think the optimal investment would be a second Moonstone and/or a full set of legendary fighter cards.
