I’ve played that composition. Supposing you’re a passive 200/200 protoss or that you took too much damage on midgame harass, so that you can’t go for the easier options (which is to deny terran B3 or outright kill him on a warpprism timing), you can also choose to accept the lategame. As a mech player, he’ll be relatively slow, and with that composition will be focused on setting a strong defensive perimeter on his first 3 bases. You can just let him do that and :
-
Take more bases (like B5-B6 while he’s saturating his third), and make enough photons so that hellions BF aren’t cost effective anymore
-
Transition to a tempest carrier disruptor composition
-
Poke the tanks (or liberators) with the tempests. He’ll bring forward his thors or cyclones to retaliate, which will make them easy prey for your disruptor novas.
-
Once the thors numbers have been softened enough, just aclic with all your air. He’ll unsiege the tanks, at which point you can just aclic your chargelot archons
-

Note that this approach requires way more micro than the usual, as you can’t just aclic him once he’s reached his 200/200 mech composition. As a protoss, you have way more options, which are significantly easier to setup.
Blink stalker tempest + photons at home.
If you’ve let him reach a thor BC composition then it’s that you’ve really slept over your screen during 10 minutes after reaching your own 200/200.
Anyway, that composition can answer to a protoss deathball head-on, but is incredibly slow and long to setup. Just runby 20 zealots alternatively on his B3 or B4. The moment for him to get there (specially once he’ll have used his teleport), either all the SCVs will be dead if it’s an OC, either the SCVs plus the base if it’s a PF.
I never reached that composition as a terran, but I think just adding more chargelots and voidrays to tempest carrier disruptor, and doing the same poking game with the tempest would do the trick once the final aclic will come. But seriously, if you’ve let him mine on his B4 with a composition like that, it’s that you’ve taken vacations during half of the game.
Oh but it is. The problem with mass air terran composition is surviving till you’ve saturated you B3. There are so much things you would die to depending on your faster commitment on lategame units (thor/BCs) ; that a protoss or zerg player could outright choose to kill you beforehand. Regarding P :
- Just use a standard zealot stalker gateball with immortals and/or archons, and either destroy or deny his B3.
- Kill him with prism zealot immortal (microed with the prism) timing beforehand
- Destroy his economy with a prism charge timing (B3 on your side while the prism is travelling)
- Wait until he has to B4 or B5, and then push with your army where his tanks aren’t sieged (on his B5 if they defend the B4, on the B4 if he goes to defend the B5. Meanwhile take progressively the whole map. He’ll starve sooner or later, and start not to have enough to compensate his losses.
Both races can rather choose to accept the lategame, but while zerg’s lategame will be rather easy to manage once reached, managing a tempest carrier disruptor chargelot composition requires significantly more micro than just aclicking the terran during a weak timing. So, why bother ?
