What abilities can you Stifle?

[Mr. Type 4]

So we were playing Type 4 and I played Blast From the Past cycle-> madness-> kicker-> buyback

What parts of that, if any, can someone Stifle, and how would they announce said Stifleing?

What about Channel?

[Anusien]

You can stifle the "Draw a card" trigger from Cycling.
You can stifle the "When this card is removed from the game this way, its owner may play it by paying [cost] rather than paying its mana cost. If that player doesn't, he or she puts this card into his or her graveyard." trigger from Madness.
You would stifle them in the normal way "Wait, I have a response.  I stifle the <foo> trigger."

Kicker and Buyback are both static abilities.

[20:31] <MitchellW> Anusien: if you are playing via madness then you can't pay the kicker/buyback until the trigger resolves

The intended behavior is probably Stifling the Madness trigger (the card remains RFG).  You'd back your opponent up to the point before they play the spell, and then Stifle it.

You can Stifle the Channel of cards like Jiwari the same way.

You cannot Stifle any part of the card Channel, though.

[Mr. Type 4]

Ok ok, so then here's what we really had an argument over, because I'm not sure I know the answer from what I can see here:

This is Type 4, by the way...

I go cycle madness kicker buyback my Blast from the Past, killing some clutch creature.  My friend Brian says, "Is there any part of that I can Stifle??"

I go, "you can Stifle the madness trigger."

So he's like, "Ok, Stifle the madness."

So then I try to play another card, some killer bomb, and he gets all mad because he says I played a card already.  Did I actualy cast a spell if my Madness trigger gets countered?

First off, please avoid 'Un-' cards as far as rules questions.  'Un-' cards often don't conform to the rules.  If you have an actual question about the actual rules (which this is, which is why I'm answering it at all), please do so using actual cards.

Madness involves a (static ability, irrel to this question, and a) triggered ability.  On resolution of the triggered ability you may play the card for it's madness cost.  If this triggered ability is countered, you never get an oppurtunity to play the spell.

[Anusien]

I'm gonna restate this in terms of Rule of Law and discarding Basking Rootwalla to Wild Mongrel, so that we can answer the question.

Let's say you control Wild Mongrel, and Rule of Law is in play.  You discard Basking Rootwalla to Wild Mongrel, and you remove it from the game.  The "When this card is removed from the game this way, its owner may play it by paying [cost] rather than paying its mana cost. If that player doesn't, he or she puts this card into his or her graveyard." trigger goes on the stack, and your opponent plays Stifle, countering it.

Play: The act of playing a spell, land, or ability involves announcing the action and taking the necessary steps to complete it.    Playing a spell or activated ability requires paying any costs and choosing any required modes and/or targets. See rule 409, "Playing Spells and Activated Abilities."    Playing a land simply requires choosing a land card from the hand and putting it into play. See rule 212.6, "Lands."    Playing a mana ability requires paying any costs, then immediately resolving the ability. See rule 411, "Playing Mana Abilities."    Triggered abilities and static abilities aren't played-they happen automatically. See rule 410, "Handling Triggered Abilities."

If you didn't do that (which you didn't in this case), you didn't play a spell for Rule of Law.

[Mr. Type 4]

Thanks guys.

I understand that Un-cards typically don't follow real rules, but Blast from the Past does, so I figured it was ok.
