I've really become a fan of going for Terahertz turn 1. Circular + 1 extender already end on Terahertz, Heatsoul and Superfactorial.
It gets really crazy when you have Circular + Parrallel ExCeed/2 extenders, then you also get access to Cynet Conflict. (counter trap)
But even when you don't have extenders or get interrupted, Transcode+Heatsoul can still go a long way.
Watch the video below for some general ideas of how to combo/play around hand traps.
