The revive consumables can only be used in the Garden Ops mode and you need use them 10 times.
Everytime you get downed on Garden Ops you will have an option to self revive and it's this who counts towards the trophy, however you can only do it thrice per game so you will need a total 4 games until you get the trophy.
It's an consumable as mentioned so if you ever run out of them, simply buy 1k packs as they appear quite often there.
You will most likely get this trophy naturally if you're going for the different difficulties trophies for Garden Ops.
There are also team revives that you can use if you lose the game but I'm not sure if these counts towards the trophy. If they do, please let me know and I will edit this guide.
