Revive is a unique fruit that will revive a player when he dies. The problem with Revive is that it is relatively bad for leveling, farming, and PVP. Damage is low, and you will have a hard time fighting against players who have strong fruits. The only thing that is great about this fruit is that you can troll other players. It is not hard to obtain Revive, so you can use it for fun if you get him, but it is better to save money and purchase stronger fruits.
What combo you will use depends on your in-game situation, who you are fighting with, and what you want to achieve. It is best to spend some time testing all possible combos, and by doing that, you will learn how to use what works best for you and also how to counter it. So go and test Revive in a game.
