So I've been playing around with overlock
and I kind of finally get that the overlock card (eye of storm, emperor Zhe) needs support so that the turn isn't weakened severely by playing one card.
This can be done with ppt and debuff
Eg eirine and infinity plague doctor etc etc weakening opponent strengthening your hand weakening theirs next turn when you play the overlock card
The issue however is still that with new buffers etc introduced by using these cards for an effect next turn and only playing 1 card you are sacrificing probably 4 deck slots 2 for an effect next turn could be better carfs, but always 2 when only one card played
Therefore overlock needs a buffer to hit either Babylon and devil, or eye stem and zhenge to around the amount of 300-600 points 3 meta cards worth of points
