one of the most powerful dark wizards of all time, who was unstoppable at the time even by dozens of Aurors of the Magical Congress. He did that without using a spell (spells were going to be useless as it'd require Albus Dumbledore type exceptional wizard to defeat him in a duel in future). He used one of his beasts. This should be popular and hit the pages of history books.

Yet, I have never encountered a wizard using beasts to fight in the main books. Neither the Order of the Phoenix nor Death Eaters used beasts to supplement their spells. Why is that?
