Why do reviver seeds only work sometimes?

Reviver seeds work all the time. If you have a partner, they revive them too. So if you have 5 seeds, your partner dies 3 times and you die twice, that's 5 times. Just don't go without a partner. They work, but for everybody on your team.

Reviver seeds work on partners too. So if you're partner dies, a seed gets used on it. That means you ran out of seeds because your partner used them all up.

Well it if you have a Reviver Seed and you die,you get a second chance,but once it's used,it won't work the next time. This item is very helpful when you are escorting a Pokemon to it's comerade. Hope this helps you out.

As long as you have Reviver Seeds in your Treasure Box, they will automatically be used when you or a partner faint.

It can only be used once, but make sure after you use one, and you have more, give them to yourself, same as your partner

I know! It annoys me heaps, I have the same problem and I don't know y it doesnt revive me probably a glitch or something in the game...

I've found out by looking in the info of the reviver seeds that you need to be an item master in your iq things for them to revive you all the time =] hope I helped

Reviver seeds is only used at once, If you faint but you have one, The Reviver seed will be used, if you faint again Reviver seed won't help you now, also, used Reviver seeds is called Plain Seeds...
