There is a 2c/4 spaceship in this rule, the same spaceship that appears in B3/S23-j:

It's not too common, but not rare enough so that rakes and guns haven't been found. In this rule, it can also delete blocks in one parity due to S3-n and B4n:
x = 26, y = 11, rule = B3-ry4ckn/S2-in3-cjn4it5aiky6-a7e8

The main attraction in this rule, in my opinion, are the spaceships. There are plenty of different, strange speeds in this rule. In the following pattern, the speeds go skrra 3c/285 (c/95, one more on catagolue), 10c/510 (c/51, one more on catagolue), 16c/480 (c/30, two more on catagolue), 13c/305, 19c/412, 16c/127 (there are 14 more on catagolue, as well as 32c/254s and 64c/508s):
