Yes, that works. In the detailed rules for suspend, "play" means "play it if it's a land and cast it if it's a spell". Since you're casting the spell, Caetus gives it convoke and Kasla will trigger from that. Just in case this is also a question: you don't actually need to tap any creatures for convoke to get a trigger from Kasla. The fact that a spell has the convoke ability is enough.

No, Hissing Miasma won't trigger Gonti, Canny Acquisitor. Hissing Miasma doesn't cause any creatures to deal combat damage to anyone. The Miasma, itself, causes a player to lose life.

Creative thought, but no, this doesn't work. To "cast" something is to move it from wherever it is to the stack, make all the necessary choices, pay all the costs etc. In this example the copy of the "when the last counter is removed, cast this" trigger will resolve first and will cast Search for Tomorrow. However, when the original trigger starts to resolve, the object it's trying to act on (the suspended card in exile) is gone and it won't be able to do anything.

No, Hissing Miasma doesn't target. An effect only has a target if it specifically uses the word "target", either in the text on the card or packed into the full rules for a keyword ability (e.g. Equip).

Are these the cards you meant to ask about? I'm just getting a funny feeling since you ask about an "interaction" but they don't seem to have anything to do with each other.

This topic has been moved to the Modern discussion forum.

The change to regeneration was part of the 6th Edition rules update in 1999 (so yeah, 25 years ago). It was part of the streamlining of the timing system from using batches, series and damage prevention / regeneration windows to only using the stack instead. Using the stack for damage prevention and regeneration effects meant they had to be in-place before the damage / destruction event actually happened instead of being applied afterward. Making prevention / regeneration work this way also meant they could use rules already established for replacement effects instead of having to use their own separate rules, which streamlined the rules further.

Those abilities don't have anything written into their targeting requirements that restricts them to "nonland permanents" or "permanents you control", so yes, you can target an opponent's lands with them. This could be useful for locking up Counterspell mana that you don't want to deal with during your second main phase, but pretty much any other kind of Instant-speed thing they could do during your second main could also be done in response to these triggers during combat, so the general usefulness there could be limited.

It's better to start a new topic for a new question rather than append it to a resolved topic, especially if they aren't related. It makes it easier for people with a similar question to find later and makes it easier for people with answers to notice the new activity (I got a notification because I posted here, but otherwise people might not look at all since the thread is marked as resolved).

You're right, Tetsuko's ability would no longer apply. If something refers to a creature's power or toughness and doesn't specifically say "base power" or "base toughness" then it's talking about the creature's total power/toughness including any modifiers.

Your opponent gets to choose the result, so they will probably choose for you to take damage.

The official current text for Spike Weaver's last ability has been updated to say "Prevent all combat damage that would be dealt this turn" to make it clear that it's a damage prevention effect. If multiple replacement and/or prevention effects are trying to modify how an event affects a player or object, then the affected player or controller of the affected object decides which one to apply first. The unused replacement/prevention effects might still be able to apply to the modified event or they might not. Since your opponent is the one about to be dealt damage, they're the "affected player" in this example.

I try to avoid marking my own responses when I do this, but in this case it was the only option.

Yes, that's the correct interpretation of what the "it's still a land" language will do here. You would have an artifact creature (that isn't a land).

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.

Yes, this works. When you create a copy of an activated ability with Verrak, Illusionist's Bracers or something similar, you aren't "activating" that ability again, just making a copy of it, so any restrictions in the original ability about exactly when or how many times it can be activated won't interfere.

Yes the myriad tokens in the Vihaan-Cybermen example will be created. A resolving spell/ability will do as much as it can and skip any impossible parts. The tokens will be created tapped, since there's no problem with doing that part, they just won't be attacking since they aren't creatures. They will still get exiled at the end of combat so you'll need to get creative if you want to make use of them.
