rather than just terrak itself, i think adaptability is the problem. i ran dual adapt mons in scarf terrak alongside sd sr dragonium chomp, and the latter ended up putting in just as much, if not more work than terrak. adapt mons just plow through everything. the -ate abilities are also stupid good and suspect worthy imo. as for terrak, this mon is nowhere near balanced. adapt with rock/fighting stab is almost impossible to switch into. this, aided by a great speed tier, makes it broken.
