I use a systemd service file to setup a bridge for somewhat similar
purposes, the sequence of commands I use is this:

/usr/sbin/brctl addbr brkvm
/usr/sbin/ip addr add dev brkvm
/usr/sbin/ip link set dev brkvm up

after that, ip a s brkvm shows:

4: brkvm: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP group default
    link/ether fe:83:79:56:a3:a2 brd ff:ff:ff:ff:ff:ff
    inet scope global brkvm
       valid_lft forever preferred_lft forever

I have never used netctl so I can't help you there, in case you are
wondering the complete service file is use is:

Description=Sets up a bride for use with virtual machines.

ExecStart=/usr/sbin/brctl addbr brkvm
ExecStart=/usr/sbin/ip addr add dev brkvm
ExecStart=/usr/sbin/ip link set dev brkvm up
