oh, i didnt get tagged for some reason ?_?
anyways, lets go. firstly, i dont really like the choice scarf set. being 4x weak to sr is really terrible for a scarfer, and scyther doesnt really shine as a revenge killer enough to make up for that, so i recommend you just remove it. however, i havent tried scarf scyther, so if any of you have used it and thought it's good, you can elaborate why and i might change my opinion.
the cb set is legit, but you are still explaining brick break in the moves section, while the move isnt even slashed. simply remove that, as bb is not a good move on scyther. also, on team options, we can build it up more. i dont think ghost types trouble scyther, making dark types good partners. the best team options are:
-rapid spinners like starmie, tentacruel, or defoggers like mew and empoleon, who have cool synergy with scyther
-other pokemon that can form voltturn cores, like rotom-h, magneton, victini, hydreigon etc.
-cleric support is ok, if they have good synergy (blissey, umbreon)
on the bulky sd, i think it should be like this:
1-sd
2-roost
3-aerial ace
4-knock off/bug bite/baton pass
i know bug bite is good against slowbro/mew/cresselia/umbreon, but imo knock off has better coverage and is more useful in general, and baton pass is really useful. team options still needs a bit of work as well; mention some pokes that can lure and weaken stuff that counters scyther (victini/rotom-h can trick/burn the rock types that wall scyther), use pokemon that lure stuff that give free turns to scyther (the mantis can easily setup on grass types, so water pokemon are good teammates, like megatoise).
thats it i think, good luck. 1/3
