I'm not good when it comes to item decision. Scizors moves are.
In case it helps. I'm running it for singles, it has an adamant nature with the technician ability. It has EVs in attack and speed. Thanks in advance again.
Your best option is a Life Orb.
Normally I would suggest a Choice Band on Technician Adamant Scizor, but you have Roost so that doesnt really work. And I'm assuming Mega Scizor isn't an option either so through the process of elimination Life Orb is the best option.
