Ah, but time + earth has other benefits. Basilisk blood + turtle shield? Plus, not ALL shrieker rushes use time marks. The AI3 doesn't. The duo still does well. I've also seen shrieker rushes that use eternity/reverse times. Reverse time/earthquake is a really devastating duo.
Still, I voted for the following:
Aether. Anubis.
Darkness. Devourer + eternity bested me in the war, and proved itself worthy.
Earth. Shrieker rush.
Entropy. Fate egg + novas.
Life. Adrenaline + dejas.
Light. Blessing + Dejas.
