Systemd daemon ignores target

Write your own daemon they said. Systemd is easy they said...

There is a small AUR package razer-blackwidow-macro-scripts 2-1 with python script that needs to be run as root (it enables extra keys on my keyboard)
Up until now I've had it in my .xinitrc

.........
sudo blackwidow-enable &  #enable extra keys
xbindkeys &  #macro keys mapping
........

Of course I've had that command allowed to be run with no password through visudo. It worked well. But I was a little bit uneasy with this solution and ppl on IRC recommended me to write a daemon for systemd instead.

Thats what I ended up with:

[Unit]
Description=RazerBlackWidow
Requires=basic.target
After=basic.target

[Service]
Type=forking
ExecStart=/usr/bin/blackwidow-enable

[Install]

But systemd blatantly ignores everything as you can see in journctl:

As you can see journal reports reaching target Basic System two seconds after my daemon started and failed (for obvious reason that kernel discovers said keyboard like two entries later).

What am I doing wrong?
Thank you all in advance for your time!

P.S. If I set

Requires=graphical.target
After=graphical.target

it fails completely rather early in boot with the following:

Jul 30 00:59:27 arch systemd[1]: Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory.
Jul 30 00:59:27 arch systemd[1]: Found ordering cycle on graphical.target/start

Jul 30 00:59:27 arch systemd[1]: Job blackwidow.service/start deleted to break ordering cycle starting with graphical.target/start

my default.target if graphical, so not sure what this is about. I use startx if that helps.
