The effect of Herald’s Horn reduces only generic mana in a spell’s cost. If that cost has no generic mana, the cost isn’t reduced.
8/25/2017
To determine the total cost of a spell, start with the mana cost or alternative cost you’re paying, add any cost increases, then apply any cost reductions. The converted mana cost of the spell remains unchanged, no matter what the total cost to cast it was.

If you don’t put the top card of your library into your hand, you put it back on top of your library without revealing it. You’ll draw it in that turn’s draw step.
8/25/2017
If you somehow control a Herald’s Horn with no chosen creature type, no spells will cost less to cast, not even creature spells with no creature type. You’ll be able to look at the top card of your library at the beginning of each of your upkeeps, but you can never put it into your hand this way, even if it’s a creature card with no creature type.
8/25/2017
You must choose an existing creature type, such as Vampire or Cat. Card types such as “artifact” can’t be chosen.
8/25/2017
You can’t choose multiple creature types, such as “Cat Warrior.” A Cat Warrior is both a Cat and a Warrior. It’s affected by anything that affects either type and unaffected by things that affect non-Cat or non-Warrior creatures.
