Daelomin at Home is discarded

[kober]

We know that “A card is not in play until it is resolved in its chain of effects. When the play of a card is declared, no elements of the card may be the target of actions declared in the same chain of effects”, so let’s assume that Daelomin at Home permanent event is already in play.

Now, what would be the outcome in the following two scenarios:
1) During M/H phase, Marvels Told is declared, and a sage has tapped to target said DaH. Would the discard be with effect (+2 HL)? Or, could a discard of DaH be declared by the Hazard player is response to the declaration of MT?
2) During M/H phase, a discard of said DaH for effect is declared and since “If an action requires an entity to be discarded as a condition for the action's main effect, that entity must be discarded when the action is declared” it’s discarded. Is there a way to stop this?

1) During M/H phase, Marvels Told is declared, and a sage has tapped to target said DaH. Would the discard be with effect (+2 HL)?

Underline mine.
Do you mean "Will be the HL increased by 2 if Daelomin at Home will be discarded in result of Marvels Told?" ?
If so, the answer is "No".

Discarding of Daelomin at Home (in M/H phase, and by its owner) is active condition of action "increase the hazard limit against one company by two".
If discarding of Daelomin at Home was not along with declaration of that action, then the action is not declared.
Once a chain of effects starts resolving, no action may be declared in the chain.

Similarly if Cram will be discarded in result of Rats!, bearer (strictly: former bearer) of Cram will not untap for this reason.

Or, could a discard of DaH be declared by the Hazard player is response to the declaration of MT?

"increase the hazard limit against one company by two" may be declared. Discarding of DaH happens at point of the declaration.

2) During M/H phase, a discard of said DaH for effect is declared and since “If an action requires an entity to be discarded as a condition for the action's main effect, that entity must be discarded when the action is declared” it’s discarded. Is there a way to stop this?

Formally it is.
By removing other conditions of the action, i.e. by removing target H/L - i.e. by removing the company.
By interrupting M/H phase, that happens when a company is returned to its site of origin.

Scenario #2 and the first part of #1 is now clear - thank you.

"increase the hazard limit against one company by two" may be declared. Discarding of DaH happens at point of the declaration.

Regarding the second part of #1, when (during M/H phase) Marvels Told is declared, and a sage has tapped to target DaH, the Hazard Player has a right to declare "increase the hazard limit against one company by two" and discard DaH at point of the declaration, therefore removing Marvels Told's target before/upon its resolution. Correct?

[Konrad Klar]

Correct.

Now, if Marvels Told were declared during any phase other than M/H (and a sage did tap to target DaH) would there be anything that the Hazard Player could do to prevent MT from resolving?

Blind to the West, Twilight (if for unusual reason Marvels Told has been played with Crown of Flowers, or if a resource, that makes the sage a sage, has been played with Crown of Flowers).
