Laning Against Ornn: Zac and Shaco's Strategies
Zac vs. Ornn
Early Game:

Zac's primary goal early game is to farm safely and avoid taking unnecessary damage. Ornn is a strong laner with high durability and crowd control, making confrontations risky.
Focus on last-hitting minions and using Unstable Matter (W) to farm effectively.
Use Elastic Slingshot (E) to disengage if Ornn tries to engage or if the enemy jungler ganks.
Mid Game:

As Zac, look to impact other lanes with your ganking potential. Ornn’s immobility can be exploited by roaming to other lanes and initiating with Elastic Slingshot (E).
During skirmishes and objectives, utilize Zac's crowd control to disrupt Ornn's initiation. If Ornn tries to engage with the Call of the Forge God (R), position yourself to counter-initiate or peel for your carries.
Late Game:

In team fights, Zac should focus on diving the enemy backline and using Let's Bounce! (R) to create chaos. Keep Ornn away from your carries and neutralize his impact.
Utilize your tackiness to absorb damage and control the fight. Zac’s ability to engage from unexpected angles can catch Ornn and his team off guard.
Shaco vs. Ornn
Early Game:

Shaco’s strategy against Ornn involves avoiding confrontations and focusing on jungle control. Use Deceive (Q) and Jack in the Box (W) to gank other lanes and secure early kills.
If Ornn overextends, consider a gank with your stealth and burst damage. Be cautious of Ornn's crowd control and disengage quickly after your burst.
Mid Game:

Shaco should continue to pressure the map through split-pushing and creating pick opportunities. Ornn’s slower mobility makes him vulnerable to Shaco’s ambushes.
In team fights, target the enemy backline. Shaco’s ability to create chaos with hallucination (R) can disrupt Ornn’s initiation and provide an advantage for your team.
Late Game:

Shaco’s role transitions into assassinating key targets and maintaining map pressure through split-pushing. Utilize your stealth and burst to eliminate priority targets.
In team fights, position yourself to flank and disrupt the enemy backline. Avoid direct engagements with Ornn and instead focus on creating advantageous scenarios for your team.

Team Fight Strategies and Execution
Zac’s Team Fight Strategies
Initiation:

Zac excels at initiating fights with Elastic Slingshot (E). Aim to engage from the fog of war or unexpected angles to catch the enemy off guard.
Use Let's Bounce! (R) to knock up and displace key targets, creating opportunities for your team to follow up.
Peeling:

In scenarios where your carries are being focused, use Stretching Strikes (Q) and Unstable Matter (W) to peel for them.
Position yourself between Ornn and your carries to absorb damage and prevent Ornn from engaging effectively.
Disruption:

Zac’s tackiness and crowd control make him a prime candidate for disrupting enemy formations. Focus on creating space and preventing Ornn from executing his combo.

Shaco’s Team Fight Strategies
Assassination:

Shaco thrives in isolating and eliminating key targets. Use Deceive (Q) to approach from an unexpected angle and burst down squishy targets.
Use Two-Shiv Poison (E) and Hallucinate (R) to maximize your damage output and create confusion.
Split-Pushing:

Shaco’s split-pushing ability forces the enemy to respond, creating openings for your team to engage or secure objectives. Apply pressure on the map and force Ornn to deal with you, reducing his impact in team fights.
Flanking:

In team fights, position yourself to flank the enemy backline. Shaco’s burst can quickly eliminate key targets, shifting the fight in your favor.
