Cyrus isn't a bad purchase if you're drowning in DCs and you need a mage for AW fodder (like me).

I'd say Spica is the only must-have purchase unless you are lucky enough to land a Nanaly. We should get more ranged melee units down the line, so Saki isn't too necessary. With AW on the horizon though, you should have a couple hundred DCs saved up after getting Spica though.

If Chydis ever comes back soon, you'll definitely want 200 DCs saved up for her too.
