"This effect is also ignored by Stall and held items that may affect the turn order: Full Incense, Lagging Tail and Quick Claw."
But not Iron ball.
Lagging tail is a good trick item, as it can cripple a sweeper while unaffecting the damage done by Gyro ball IE: Bronzong. also works well with payback, metal burst and some
Sub+focus punch sets.
Iron ball works well on trick room pokes as well as empowering Gyro ball. It also has some use tricking onto flyers that can then be EQ'd or arena trapped by Dugtrio. Also placing it on a floating poison-type will allow it to absorb toxic spikes. (lol Curse+Gyro ball Weezing, so long as it isn't switched in on EQ.)
