How does Black Horn work?

[You must be registered and logged in to see this image.]

Code:

When your opponent would Special Summon a monster: Negate the Special Summon,
and if you do, destroy it.

This is how Black Horn works:
It only works on Inherent Special Summons. Inherent special summons are done by a Summoning Procedure either by its own Summoning mechanics (Synchro Summon, Xyz Summon), a Summoning condition or by an Effect without Classification that allows it to be Summoned that way.

Black horn of heaven cannot be used in response to a summon. It can only be used to negate the summon of a monster that is not on the field nor in the hand, yet. If horn is activated it is not the time at which bottomless or other cards are played, it is before that.

So, here is something to remember
Anything maxx c cannot chain to, Black Horn can negate that summon
thunder king rai oh works the same way as Black Horn.

Also just a side thing to add so it's a bit easier to remember, Horn can not negate cards that summon monsters (Polymerization, Gem-Knight Fusion, Call of the Haunted, etc) but it can negate summons that don't start a chain (Synchro Summon, XYZ Summon, etc)

No I just like helping know things better, you'd be surprised how many people DONT know what Horn can and can't negate.

No because mst does not negate.
Also you cannot chain mst to black horn.

no since Mst is speed 2 and black horn is speed 3.

100% Sure that was a troll question.

Well, since it is answered, LOCKED.
