This one has a very nice Unique Rectangle that solves it in one step. I think you could do it that way.

But, if you do not use the UR, it is very interesting. And, no, my solution does not use Medusa.

Code:

OK, here's my story. I ignored the Type 2 that appeared very early. I used an XY-Wing with pincer coloring, followed by two W-Wings. After that, basics finished it off, although there did appear another Type 2, then a Type 1 a little later.
