Buring-tree emissary

[Antirayman]

Can you respond on {Burning-Tree Emissary}s ability.
I'm not sure, because it's a mana ability.

It gets put on the stack but responding to it won't make it go away, the only way to stop it is counter the ability or the creature itself

Also, it isn't a mana ability. It's an ETB trigger that adds mana to your mana pool.

Usualy you can't respond on mana abilities but those abilities are activated abilities.
That's why i'm asking.
Not how i can counter it

{Stifle} or a similar effect will do the trick.

According to rule 605 (sorry don't know how to link rules) any ability that causes mana to be added to the mana pool is a mana ability. The only way to prevent getting the two mana is to prevent the emissary from entering the battlefield.

It is not a mana ability, see keys post.

I did see keys post. It didn't sound right so I went to the rules. 605.1b defines a triggered mana ability. 605.4a says, among other things that triggered mana abilities don't use the stack so can't be countered. I realize that I'm going against the tide here, but this is a contradiction that deserves clarification.

Key is very knowledgable and I find him very helpful, but that doesn't make him always right. I've given a rules reference. Sorry I don't know how to link them. I'm asking for clarification on either how I misinterpreted the rules or another rule that I missed that covers this situation.

The people have spoken, there shall be rulings!

Here's what you were referring to, yes?

605.1b A triggered ability without a target that triggers from activating a mana ability and could put mana into a player's mana pool when it resolves is a mana ability.

This talks about a trigger that goes off when you use a mana ability. Something like this would read "whenever you tap a land for mana..."

This is not the case, however. What we have with the Emissary is an ability that produces mana, caused by an ETB trigger. The following rule applies to this situation:

406.5. Abilities that produce mana but trigger from events other than playing mana abilities do use the stack. So do abilities that don't produce mana but trigger on playing mana abilities.

It produces mana, but not due to a mana ability (like the above example I gave would). That being said, it is a triggered ability, and uses the stack/can be responded to.

For the record, I'm never against someone going against my statements, so long as they have reason. Hope this cleared things up!

According to this

It is NOT a mana ability, uses the stack, and can be responded to. So {stifle} effect will work or {counter spell}s. anything that counters a spell will stop it.

Thanks. It was informative and the answer I was looking for.

ONLY {Stifle} and others like it can counter the ability, {Counterspell}s can only stop the Burning Tree from resolving.
