A stable snoitreneg rule with common P4 oscillators and a c/2o. Still lives exist although they are fairly uncommon.
The P4 oscillator can eat the c/2o and the c/2o can pass through the P4 destroying it.
In fact, any oscillator and spaceship pair that each have consist of only one state and have opposite states are able to destroy the other without being affected.
