any team with a healer nullifies that, infact, most pokes fall easier to the rest/sleeptalk/wrap/toxic set, power trick is too hard to impliment in single battle, since almost any physical attack takes shuckle out after the trick
and to make the sets i've mentioned successful, less effort is needed for the same effect with other pokes and other sets, either swagger/psych, swords dance, or other pokes using power trick
the counter is too simple, and making use of it is too complicated, but shuckle is fine as it is so it isn't all that bad...
i rkn it's safe to say P/D has effectiveli eliminated the tier gaps with the physical/special split (and providing evolutions for the less useful pokes... (erm but some are already overpowered...) the tier 1 pokes as we know it seem pretty weak all of a sudden...
