>>38276975Scizor's stats and movepool complement its stats and ability quite well.
It's bulky with a good defensive typing, reliable recovery and technician bullet punch to overcome its speed coming off a very high attack.
Syther is much less efficient. Both its attack and speed are above average, but not impressive. Its eviolite boosted bulk is good, but undermined by its type. It has no worthwhile priority like Scizor's bullet punch. It can't even abuse U-turn like Scizor because Stealth Rocks kill it.
