Forretress has always struggled with opposing spinblockers due to its utter lack of offensive presence. Wouldn't it be great if Forretress had a move that crippled Ghost Arceus and non-Restalk Giratina(-O) at the same time? Enter Toxic. If you can predict the switch (it's not terribly hard if you're decent at that kind of thing) you can poison them when their defenses are down, giving them a death sentence. Toxic is also good for miscellaneous other offensive threats, especially if you aren't running Gyro Ball.
