Drill is coming back a bit because everyone is running Leftovers Lando instead of Rocky Helmet, which does beat Drill if you're willing to take a Toxic (depends what the drill player wants to do). It will usually end up with both sides having SR on the field.
There was a team running around with double suicide leads in Drill and Gren, so you got rocks, spikes, and tspikes. Gren packed Taunt and Ice Beam, but I think Shadow Sneak could be in the last slot instead of Ice Beam to spin block (but who spins now), so I guess Ice Beam was the better option.
Diancie lead is becoming a thing, if you run Max HP you can take an EQ from Jolly Drill, Lando, Chomp in regular forme and then get up your own rocks, then Endeavor the next turn. It's definitely not a traditional suicide lead (and you are wasting your Mega slot on it), but like lead Heatran and Lando it can catch your opponent off guard.
