Exactly -- rules. Like I said, if you're using a single example, you're basically just writing a coded version of the rule. In itself, this isn't a bad thing -- if you're a beginner and all the technical jargon is new to you, then it's easier to memorise an example that illustrates the rule than the explicit rule. Either way, though, that's only declarative knowledge, and constantly revising declarative knowledge won't get you closer to automatic procedural knowledge.
The way I use it is to set up decks by grammar themes that I find difficult or tricky. For example, I have a deck devoted to the imperfect of the subjunctive verb form. I have around 40 entries there, and I might add more if I see something really interesting. I have a deck for hypothetical statements. I have one for prepositions that go with certain verbs. Etc. And I've just started one with some really tricky pronoun usage that I would like to master. It's great to be able to leaf through a set of examples that focus on a certain theme.
This doesn't really sound much like SRS though. If your deck is that small, you're presumably ignoring the algorithm and doing things whenever you feel like it, much like if you opened up a grammar practice book, but with the added advantage of the questions coming in a random order. I'm guessing you often just tell Anki to revise ahead of schedule, as otherwise the set of questions will be really small.
That's OK, and fair enough, Anki just happens to be the tool you have to hand, but it could just as well be an Excel spreadsheet.
But it's still not really "massive", and it stays predictable, so there's still a risk of memorising specific examples rather than generalising the rules.
