Although this is influenced by the taste of the player, each Champion has different gameplay, making their ways of Ganking different.

When the enemy is pushing, under the tower, it is best to go through the river (in Summoner's Rift), using your ultimate on him will prevent him from escaping the tower, in addition to generating great damage, Relentless Claw will generate even more damage, and with the help of the turret he will die easily (Depending on the enemy), although you can use Hunter's Call and insist with basic attacks if it was not enough.

Hunter's Call can be a major upgrade when ganking in the presence of an ally, especially if they are a ranked champion, as you can take either the kill or the assist.

To ensure the survival of an ally, it is best to use Hunter's Call when he is within his Effect Range, as this will allow him to defend himself better, in addition to giving you advantages in 1v1.

An easy way to steal the buffos is to wait in a bush for the enemy to eliminate the camp, possibly with reduced life, so a surprise attack will give you a sure kill and the buffo.

You can also Steal the Dragon or Baron upgrade from them using Punishment, although this is quite dangerous, and even difficult to achieve.
