I understand chans/bliss combo is unhealthy, and gengar sure is a powerhouse to be respected.
stall teams do benefit from these two pokes......but so does offensive team! With bliss, an offensive team could build its defensive core around just one def and one spdef wall and some nice predictions. examples: skar/bliss/jolt, forre/bliss/cb k9 and the obvious wee/bliss combo
and Gengar alone with focus punch can disrupt most wall teams , as sp walls are mostly weak against fighting (pory/lax/bliss/chans/umb), and few def walls can take a tbolt/hp ice combo.
What Im trying to say is that bliss/gengar are key pieces to make an offensive and effective team. Without gengar, its f-ing hard to get past sp walls, and without bliss is f-ing hard to have a effective defensive core with only 2 walls.
and for those who complain about chans/bliss combo
just my opinion tho
