Hi,

They come handy. I also use both. I am still figuring out how Magic works, atm I just realized how good these 2 x 2 work together (already wanted to swap Crystaltech Scholar, because I didn't really understand its function):

I still don't understand why sometimes I get the mana unlock, and why sometimes don't. Probably something to do with the fact, from mana 5 it grows further in every 2 turns, not 1. Still nice to have 9 mana unlocked, when opponent has only 7. 😉

I find Magic slow, too compare to Nature, but now I see, it's worthy, I have better results, just knocking on the Gold doors.
