Which monster do you like the most in Heroes 5 at level 5?

Many people say that Hydras are good, that while they hold the line, a highly upgraded hero can obliterate everyone with Chaos magic. However, the poll doesn't mention a Hydra with an upgraded hero; it only includes the Hydra and its six-headed upgraded version. Therefore, in various tactical formations, I don't rule out that Hydras can be effective, but we generally prefer to attack, and in that regard, Liches and Unicorns are clearly the leaders! Although, I can't help but criticize Unicorns; I've only seen their blinding ability once. On the other hand, the Liches' ranged attacks have always caused me problems, and eliminating them has become my top priority!
