First thing to do is learn how to drill whenever you want. HCBx2 is not as hard as it sounds.
Once there, the setups are easy as hell.
Bait out low fierce or poke, roll, drill…
Lowjump short into drill…
bait them into expecting a s.roundhouse and rolling, then drill (this has the double benefit of setting up a ‘will i drill or guillotine’ mindgame. A lot of my matches with Yama is spent with me just out of roundhouse range making my opponent second guess himself.)
Set a P/K-Groove player up to expect a guillotine jumping in, then drill instead as they land. This is actually easier to do with a level 1 than a level 3.
After a landed headbutt, stay near their body and make them think you’re gonna go for a drill. Whiff a low jab as they get up, and then drill anyway. This is only to counter people who think they have eye of the tiger
If you’re in close range and can spare the meter, just drill. I mean, really, what they can do to get away? If you see them just standing there, input HCBx2 and if they still haven’t moved, you have them.
And finally, you can just roll into super.
