I have never liked the simisear line, but now i find something inside of it. Well, after the egg has hatched (and named him "Fiery Shadow" because i mixed the fire with the DARKNESS), the first thing i did was to bring it at lvl 100 with the chansey strategy (absol with false swipe...). Now, with a pansear at lvl 100, i got a fire stone and evolved him into a simisear. I used the berries to reset all unnecessary evs, and i used the correct items (power weight, power bracer...) with pokerus to but him good EVs.
