The first couple of hundred ticks almost noone defends, I don't see why zik/ter DE should have any problem whatsoever roiding Etd and Cat during that period. ALso, many terrans and ziks are unlikely to have hulls 3 early, so you can hit them early on too.

ALso, incase you haven't notice, Ter and Zik both have other fleets to attack with than DE; maybe use them early and switch to DE later? Alternatively, don't go Ter and Zik.

edit: it's also very possible for caths to attack some races with DE + co pods
