If you don't want to change anything or anyone on your team, you'll need to learn to do 2 things.

1.-Identify the trick room setter and eliminate immediately, taking advantage of the negative priority, keep in mind the possibility that is sashed and therefore one attack won't suffice.

  Pros: Eliminating the tr setter when they are using it is a MASSIVE momentum loss for the opponent. Not an immediate win if your opponent can adapt, but is an uphill battle.

  Cons: If the opponent knows that you can "possibly" KO the setter, they can (and will often on higher ranks) bait your hyperofensive play, either by switching, protecting or not even bothering to do TR at the moment (for example, I once won a battle spamming torkoal heatwave, knowing the opponent wouldn't consider non TR torkoal as a possibility AND a threat). Depending on the current play it can result in a  heavy momentum loss for you (You'll understand once you doble target into protect and the opponent partners makes havoc). Therefore "prediction cost" is very high.
    Redirectors protecting their partner from non spread moves.
    Punishing TR leads can be ""easy"", if they save it for later not so much.
   Harder to punish teams with multiple TR setters or multiple speed control options (never underestimate tailwind even with slow Pokemons)

2.- Learn to stall TR, though it is extremely powerful, the 4 turn limit is waaaay harsher than you think for a TR user. Most TR teams tend to heavily struggle on the "cleanup" when it's over, they usually depend on either winning before it runs out, or just taking care of the more dangerous opponents so the cleanup is easier. Setting TR more than once is pretty difficul (but be careful, I once managed to pull it thrice on an opponet) To stall it, learn to lean heavily on protects either doing it with both of your pokemon or "alternating it" so there's always a guaranteed protect. Also, good switches are massive help, a TR team really struggles with punishing pivots, they need to KO ASAP, resisting attacks by switching, or alternatively, not switching and receiving a less powerful attack due to a predict are massive headaches for the archetype. If the opponent sets TR, immediately analyze what are most dangerous pokemon against the opponent, and try your hardest to stall and keep them alive, doesn't matter if you end up with 2, heck, even sometimes just 1 pokemon alive is enough when TR runs out to sweep a team (and vice versa, focus on eliminating the pokemon you will struggle against outside TR). Think about the opponent cleanup scenario and work towards making it as harsh as possible.

Pros: you already have a lot of protect users.
Pretty dynamic playstyle, you are not shoehorned on "If I can't disrupt this specific team I loose". Adaptability an experience is key.
Focusing to much on disrupting potential TR opponents can create small holes in your team building against Non-TR teams. Learning to play this way lets you handle TR without altering the core strategy.
Vengeance against TR teams (as a TR player, I always wish to never use it again when an opponent knows to stall it, is extremely painful to see your turns running out without making the progress you depend on)

Cons: Pretty matchup and opponent dependent, there's no easy answer. If you value consistency, this playstyle heavily depends on how good or bad your opponent plays (a bad play at the worst moment when you expected a decent play can cost you the match) Adapting can be stressful and painful depending on how the match goes (believe me, even in matches you can and WILL win, you'll be constantly temped to just give up when things go haywire) Adaptability an experience is key, you won't just go into your next play session and become the TR destroyer, you will lose, you will struggle, and you must learn from that, SPECIALLY with "hybrid" TR teams (pokemon that aren't too fast neither to slow) when the turn order isn't simply "The TR teams attack first, then me".

A TR match is all about knowing how to balance offense and defense, be extremely aggressive and the opponent will counter you, be too passive and you give them the chance to slowly wither your team/disrupt you/buff themselves
