Decks to pick up while waiting for Ascendency to be released?

So I am a prospective new player who just backed Ascendency and pledged the core set. But I also want to dip my toes into the game now rather than waiting for Ascendency to be released.

The Master set would be the obvious answer, since it is best bang for buck, but it seems way out of print, so maybe not realistic. Thankfully POD seems already up and a lot of retail decks are still available too.

What 2 decks would be good to start with? And which next few would be good to round out a good starter pool of cards for deck building/draft?

(I'm mostly looking at PVP atm, since I am not sure if the Red Rains Chimeras will be added to POD later and want to avoid FOMO factor)
