The actual number of times Marneus Calgar is triggered by Tempt with Bunnies
I was watching an episode of MTGGoldfish in which they were discussing some fake group hug cards and the Temp with THING cards came up and specifically [[Tempt with Bunnies]] and Phil mentioned its synergy with [[Marneus Calgar]], they were confused about it a bit, unsure if it really worked the way Phil said. Later in the video around the 22:46 mark they mention how they got an answer from a judge about the interaction and the answer they were given is one that I disagree with. So, I did some digging and found that a lot of people believe the same wrong answer their judge gave them is correct, posts on r/askajudge and rules pages on Facebook have people stating what I believe is the wrong answer. So, I made THIS VIDEO to explain the correct result and provide some extra context and scenarios that look similar but are different. I know videos are not for everyone, so here is the written basis for this and I hope anyone in the future looking for this answer stumbles to this post/video rather than one with an incorrect answer.
PERSPECTIVE
In the Comp Rules, there is this one (CR 700.1) that explains how the same event can be interpreted or treated differently based on slight wording differences. An example I like to give is if you equip your [[Infiltration Lens]] to your [[Anzrag, the Quake-Mole]] and then you attack and the opponent double blocks it with two creatures. There will be a total of 3 triggers, two from the Lens and 1 from the Anzrag, and this is all due to how their trigger is worded.
THE SCENARIO
So the scenario that came about in that Goldfish video and that I have seen a lot of debate over is this, you control Calgar and then you cast the Temp with Bunnies and when it resolves all 3 of your opponents took the tempting offer to draw and make a token. This means that the TwB will by itself net you a total of 4 cards drawn and 4 tokens made, but the question is over how many times this triggers Calgar. Some players believe it’s 2 triggers, once for the token you always create from the TwB effect and then the other 3 are created at the exact same time which falls into the "or more" part of Calgar’s ability and therefore only get one additional trigger from him. Others believe that you get 4 triggers from Calgar, 1 from the token you make and then 3 other individual triggers from each of the tempted opponents that netted you to make 3 additional tokens.
THE CONFUSION
I think that the confusion over this stems from the fact that for a lot of Magic cards and their effects, you can tell how many times an event happens by reading the number of times the action word shows up. If a card like [[Snort]] deals 5 damage to 3 different opponents based on the choices they made, it's not dealing the damage 3 different times because it only says the word "deals" once in the instructions. Compare this to cards like [[Collective Defiance]] and [[Fiery Confluence]] that do have the word "deal" multiple times and now you do have a situation of damage from a single effect being dealt multiple different times.
So, there is another "Tempt" card out there, [[Tempting Contract]] and it looks oh so similar to TwB, one obvious difference is that you don't always make your own token, this one only has the 'get things based one what your opponents chose' part, but there is also something else different about it that is the biggest difference and I think this is the largest reason for confusion.
THE ANSWER
So, if you controlled Calgar and resolved that Tempting Contract with all 3 opponents taking the temptation, Calgar would only trigger a single time. The reason is that there is a single event of you creating 3 Treasure tokens and that hits the "or more" aspect of Calgar's ability, so only one card drawn from Calgar. From this, we can extrapolate that the TwB should be 2 triggers for Calgar, once because the TwB instructs you to "create" a token and then later in the effect it instructs you to again "create" tokens, so that's two mentions of the word "create"... BUT... that isn't what actually happens.
The answer is crazy enough 4 triggers for Calgar. The reason for this is because the TwB also has your opponents and more importantly you draw cards as part of its effect. So we now need to check out CR 121.2 as well as CR 121.2 because they have some rules that make it so that all cards in Magic are drawn only 1 at a time, they can never be drawn in mass simultaneously. To which we then have to seek out CR 608.2f which has a ton of text, so I'll summarize that it basically says we normally do handle instructions like this simultaneously but if we're unable to do that then we break the instructions down into parts we can legally do. Because of the card draw aspect of TwB, we have to break it up into individual parts.
So TwB is telling us to "create N tokens and draw N cards" with N being 3 in this case, but due to the rules it ends up becoming "create 1 token and draw 1 card and do this N times". I made THIS IMAGE to help visualize what is actually happening here, so I hope that helps if this GIANT WALL OF TEXT was a little much. So, if someone is looking for a TL:DR part, I guess that image is it with the context that card draw as part of TwB effect is the reason it unfolds this way.
