I really, really do not want to see Technician on this. With Technician, Ancientpower would instantly become the primary STAB move (unless, of course, we give it something new as well), and that means every CaP 5 is going to be using a move with a 10% chance of an insanely powerful side effect. +1 speed CaP 5 will outspeed all scarfers and Deoxys-S, and with +1 special attack there's going to be very little besides Blissey that can safely take a hit from it. Obviously, 10% chance isn't exactly big, but it WILL happen sometimes, and the huge luck element that it would introduce is something that I don't think any of us want to deal with.

Should we bother with a new move? Yes
