Actually that's the entire reason I use them: any strategy's power is amplified by how unexpected it is. If you do something
totally unexpected, like attack speed veigar, it will be useless because there's nothing to amplify really, but it will perform better than you would
expect it to, just not viably. The key is to find something as or nearly as good as widely-known strategies but totally unexpected and difficult to decipher.
To put it in a concrete metaphor, a really resilient tank everyone ignores would be worse than a slightly softer tank that always gets focused and chased by enemy squishy carries; it's not just raw theoretical effectiveness that matters, but also how the enemy reacts to it.
For further reading, see Sun Tzu's Art of War, which, aside from a lot of how to deal with your subordinates and conquered peoples, is mostly
about being unexpected.
