A pretty easy way to dial back the power on Valin Draco's ability while preserving the theme is just to change the timing window. Looking at Gyroscopic Targeting gives a good template.
- At the start of the Combat phase, if you decloaked this round, you may choose an unstressed ship at Range 1 and assign a stress token to it.
or
- At the end of the Combat phase, if you decloaked this round, you may choose an unstressed ship at Range 1 and assign a stress token to it.
O-66 could read similarly.
- After you perform a white maneuver, if you decloaked this round you may receive 1 stress token to rotate your ship 180 degrees.
