This is also effective against targets that are re-spawning with the Guardian Angel buff, placing Yordle Snap Trap under them provides a definite kill.
You can fire 90 Caliber Net away from opponents to close the gap when chasing.
Inversely, it can be used as an escaping tool as well, slowing the opponent and propelling you away.
90 Caliber Net's recoil will immediately stop you when you hit terrain that is too thick to move through.
Caitlyn can use 90 Caliber Net to hop over thin walls in the jungle, creating a quick escape route out of dangerous situations. She also can use this functionality to pursue enemies effectively. As it uses a bit of mana and has a long cooldown, it should be used with caution.
When you rapidly use 90 Caliber Net and actvate Piltover Peacemaker right afterward before moving (helps to use smartcast), you move away as usual but your Q also goes off from where you were standing before moving with no animation.
Avoid using Ace in the Hole in large team clashes as it might be blocked by another enemy champion. The cast also cancels if the target dies prematurely.
Using Ace in the Hole at an angle that the enemy team would not expect makes it more difficult for it to be blocked.
When an enemy flees at low health, you can finish them off with Ace in the Hole. However, remember that it can be intercepted, so try to find a clear shot first.
Because Yordle Snap Trap grants vision of an enemy who steps on it, be sure to place them strategically and keep an eye on them. You may be able to get a surprise Ace in the Hole off of someone who triggers it in the bush or jungle, allowing you to either hurt them to prevent a gank or finish them off if they fled to the jungle.
