You think they'll both see a rise in a metagame with Zamazenta? Scizor pretty much can't touch Zama unless it's running Superpower and I don't really see it using that move over his other options. The standard Weavile sets also get walled by Zama
Scizor @ Heavy-Duty Boots
EVs: 248 HP / 168 Def / 92 SpD
- Swords Dance
- Bullet Punch
- Knock Off / U-turn
Scizor @ Leftovers / @ Heavy-Duty Boots
EVs: 248 HP / 8 Def / 252 SpD
- Bullet Punch
- Knock Off
are currently used, the former is used to tank hits better from choice band kartana and rillaboom, where the latter is better to check special attackers such as kyurem, tapu lele, and clefable with thunder in its arsenal. Both sets have their merits in the current meta, but which set you should use depends on your team entirely.
currently there are plenty of scizor teams which tend to be rather offensive with partners such as weavile, rillaboom, hawlucha, volcarona, garchomp, tornadus-t, and tapu koko, as they can put a lot of pressure on plenty of common pokemon and they easen the teampartner up with great synergy while maintaining the offensive pressure. this is mainly why scizor has risen in popularity recently. also it is one more knock off user with a boosting move in swords dance and knock off users in ou are in general very appreciated to remove annyoing items such as leftovers and heavy-duty boots.
these are the main reasons as to why scizor has found a place in the current metagame and i think it'll see a rise in the viability in the future as well, as this pokemon alongside weavile really left a big impact recently.
