ofc pursuit does half of that, and full that when switching out
252 Atk Tyranitar Pursuit vs. 54 HP / 232+ Def Wobbuffet: 138-164 (25.8 - 30.7%) -- guaranteed 4HKO after sandstorm damage and Leftovers recovery
(138, 140, 140, 144, 144, 146, 150, 150, 152, 152, 156, 156, 158, 158, 162, 164)
Counting SS, this has chipped off minimum half your life if you encore+counter (with sitrus, you have 125% life, it does 62.5% around), up to 10% more. Also worth noting;Counter won't one-shot back on a pursuit without rocks support.
In fact, counter won't one-shot a support set at all if it uses pursuit, unless you have a lot of prior damage (about 30%), so it can pursuit three times there (or mix it up with a special move).
So, yeah, i'd like this to be mentioned as a counter. More realistically, i'd like "pursuit" to be the counter instead of Bisharp, and just give a very strong mention to Bisharp, a somewhat mention to Tyranitar, and somewhere there throw out that any pursuit can be problematic (does bandzor still use pursuit? Hell, does anyone still use bandzor?)
Edit: and i should explain the real reason. Even though you can kill tar, it's capable of stacking a lot of unavoidable damage on you. As Wobb, your job's to revenge shit your team needs revenged, but if you take out tar instead (which your team might not give a shit about) it's kind of a problem. Yeah, tar's pretty lukewarm against you overall, but it's hard to check or counter a Stag mon and tar is at least doing an okay job at checking you.
Realistically speaking, Wobbuffet gets worn down a lot after using Encore at times, so I really do not think that Tyranitar has any advantageous matchup against it, especially since Wobbuffet should almost always be paired with a Healing Wish user to take an immense amount of pressure off of it. I admit that I miscalculated Pursuit, and while Wobbuffet does take a notable amount of unnecessary damage, one instance is not really enough to justify putting it into checks and counters, since Ttar does not consistently beat Wobbuffet to begin with.
AM Check implemented.
