604.3a A static ability is a characteristic-defining ability if it meets the following criteria: ... (5) it does not set the values of such characteristics only if certain conditions are met.
Arixmethes's ability doesn't meet the definition for a CDA.
It doesn't matter for this question since the printed ability will always have an earlier timestamp than the later resolving spell, but it is important to point out.
Kudro's triggered ability targets the card to be exiled. Thus the choice must be made when the ability is put on the stack. Cards that enter an opponent's graveyard later will not be a valid choice as target.
In the most common case, you cannot do what you propose.
Most such effects are similar to, "Target player sacrifices a creature."
In such a case, the choice of object to sacrifice is made while the spell or ability resolves. During this time, no player can take actions like sacrificing to pay for another spell or ability's cost.
In the much rarer case of an effect that reads similar to, "Choose target permanent. Its controller sacrifices it.", it's a different matter. That chosen object is locked in when the spell or ability is placed on the stack. Players are free to interact with the chosen object before the spell or ability resolves.
Neither of Riku's abilities target. If the object to be copied is not in the expected zone, the game will use last known information about the object to create the copy.
If they sacrifice 100 goblins I take 100 damage despite the dissipation field? The damage is applied all at once and not as separate 1 damage triggers?
There are 100 separate 1 damage triggers, but the abilities exist independently from their source. As long as they get all 100 Bombardment abilities on the stack before the first Field's ability resolves, the Bombardment abilities will get to eventually resolve despite the Bombardment permanent no longer being on the battlefield.
Also you may not be aware but there is an ability known as split second. You make ask for strategy advice concerning its use in other parts of these forums.
That rule doesn't say it's on the battlefield. It says it's part of an object on the battlefield. Not every quality of a whole is true of any part.
>>> Actually, the puzzlement I have is settled by an answer to one question, attached at the end.
If the card is an object and it's on the battlefield then the rule defining them says it IS a permanent. We know there has to still be object semantics for components of a merged permanent. CR 721 is loaded with ways that we still treat components as having the complex qualities of objects, like face-down status for example. Their being objects is not in question.
The intent is that some objects have components, and the necessity is that components are objects. The components are always cards, and those cards represent the object made of those components, and certain references to components pass on to the object merging them and vice versa. But the components are no longer meant to be addressable by player choices. They can't be targets & they can't be chosen as attackers.
The question:
If my opponent merges two cards without flash, & I gain control of the merged permanent, & my opponent controls Teferi, Mage of Zhalfir, does a Mutual Destruction I cast have flash (triggering my Slitherwisp) ?
You reading too much into this.
It is no different than meld cards. Each card is on the battlefield but is not coterminous with the permanent it represents, rather one of several components of that permanent.
Since the cards are on the battlefield, both the original and mutating card don't have flash as per Teferis rule text.
Adventurer cards have two sets of characteristics.
When you go to cast the card (usually from your hand) you choose either to cast the creature part or the instant/sorcery part. That choice determines what spell goes on the stack. There is no ability involved.
As for your second question, you may cast the creature part of the card from exile immediately, assuming it is otherwise legal. Creature spells normally have what is called “sorcery timing”. You can cast them during your own main phase when the stack is empty. Nothing about Adventurer card rules changes this timing.
FYI
Strictly speaking, the ability triggers when the mutated cards hit the graveyard, at which time only the God-card actually has the ability.
However, an ability that trigger 'when a creature dies' is called a 'leaves-the-battlefield ability' (rule 603.6c), and this kind of ability has the privilege of 'looking back in time' to establish which cards are affected (rule 603.10a).
603.6c Leaves-the-battlefield abilities trigger when a permanent moves from the battlefield to another zone (…)
603.10a Some zone-change triggers look back in time. These are leaves-the-battlefield abilities, (…)
Actually Wizards' official language on LTB abilities are that they trigger from the battlefield, not the graveyard (or other zone). See the wording of the Oracle rulings on Yixlid Jailer.
The last sentence of C.R. 205.1b was added with the rules update for Throne of Eldraine. According to the update bulletin for that set, the sentence is intended to modify the "artifact creature" exception to the general rule that if "an object is said to become a certain list of types, these overwrite any other types it has" (review C.R. 205.1a).
Thank you.
I was leaning towards the last sentence controlling based on the general principle that when two rules exist for one event the stricter/more restrictive of the two controls. Based on the new information that the last sentence is the most recent addition to the rule, that cinches it for me.
205.1b Some effects change an object’s card type, supertype, or subtype but specify that the object
retains a prior card type, supertype, or subtype. In such cases, all the object’s prior card types,
supertypes, and subtypes are retained. This rule applies to effects that use the phrase “in
addition to its types” or that state that something is “still a [type, supertype, or subtype].” Some
effects state that an object becomes an “artifact creature”; these effects also allow the object to
retain all of its prior card types and subtypes. Some effects state that an object becomes a
“[creature type or types] artifact creature”; these effects also allow the object to retain all of its
prior card types and subtypes other than creature types, but replace any existing creature types.
Inkmoth Nexus' effect uses the "still a [type]" language so all the object’s prior card types,
supertypes, and subtypes are retained.
However, the effect also uses the "[creature type] artifact creature" language, so the object [is] to retain all of its prior card types and subtypes other than creature types.

Nitpick:
Or it's color defining CDA, of which there are currently exactly two such cards. (Transguild Courier & Sphinx of the Guildpact)
Not true.
In the reverse order, the returned Child will get destroyed by the old Child's triggered ability. (And the new Child sets off another dies trigger.)
Currently tokens phase out and in just like permanents represented by cards (or by both tokens and cards in the case of merged permanents).
Idol of Endurance's ability cannot be used with bestow, mutate or the Adventure (instant/sorcery) half of Adventurer cards.
Bestow:
Adventure: Casting the Adventure half would result in a non-creature spell being cast in violation of Idol's ability rule text.
There are 100 separate 1 damage triggers, but the abilities exist independently from their source. As long as they get all 100 Bombardment abilities on the stack before the first Field's ability resolves, the Bombardment abilities will get to eventually resolve despite the Bombardment permanent no longer being on the battlefield.

MoC is the only creature that can legally be declared an attacker: You must attack with MoC.
There are exactly two creatures, one of which is MoC, that can attack: You must attack with one of the creatures. It is your choice.
There are 3+ creatures including MoC that can attack: You must attack with all creatures except MoC.

Which is it?
