Back at Splinterlands after 2 years.

I played Splinteralnds back in the days (still called Steemmonsters back then).

After a few months of not playing I sold all my cards (yeah much regret) but still didn't do anything with the dec I got.

Now I logged back in an saw I have 600K DEC lying around.

I only have a few basic cards but wanna invest at least have of the DEC I have to buy a decent deck.

Many new cards and stuff makes this a bit difficult but playing a ton revealed the new meta and now I'm about to buy some cards.

Anybody can suggest me some must have cards (and the reason why)?

Thanks guys!
