If I have both Fires of Invention and Underworld Breach out on the field at the same time, can I cast two cards from my grave by only exiling for escape without having to pay the mana cost? or does the escape cost count as an alternative cost and not apply towards Fires of Invention's ability?

This is a great clarification. Thanks!

If I have Vilis, Broker of Blood on the field and my opponent plays Sheoldred, the Apocalypse on their turn, they create an infinite loop which would cause me to die on my draw step.

Assuming I have 5+ available black mana after my untap step for activating Vilis's "{B}, Pay 2 life: Target creature gets -1/-1 until end of turn." ability, is there a way to order the stack to kill the Sheoldred before I draw?

My gut tells me no because every time I activate the ability, a loss of life event occurs and places another draw trigger on the stack between each -1/-1 event. I'm not sure if that's correct and I don't understand why it's correct if it is.

Could someone explain to me in steps how the triggers enter and leave the stack as well as what are different ways to manipulate that order by holding priority or letting some effects resolve before activating others?

I read a post explaining that Farewell resolves one at a time in an order due to rule 608.2c. According to rule 603.3 if any of these exile events would trigger an ability due to a permanent leaving, those abilities would go on the stack to resolves after the entire Farewell resolves.

So if I understand correctly, if a Farewell exiling everything but creatures goes on the stack and there is a creature with Animate Dead on the field, the Animate Dead would leave the field first, but the creature would not be sacrificed until after the the Farewell has completely resolved. Therefore, the Exile all Graveyards line would not exile that creature from the graveyard because it had not been sacrificed yet.

I hope my understanding of these rules is correct up until now. Where I get confused is things like a post I saw saying that on Arena, a Portable Hole gets exiled and a creature permanent coming back would also be exiled. Is this due to a state based actions and not a triggered event?

Further confusion is, if you have a creature that for whatever reason is only being kept alive by an artifact anthem effect such as a Vanquisher's Banner and someone plays a farewell without the graveyard line, would your creatures go to the grave by a state based actions of the Banner leaving and having 0 toughness prior to the Exile all creatures line hitting them?

I just have a general confusion about this card and when the one line of text resolving at a time would be relevant or not.

Makes sense! Thanks for the clear explanation.

I have a few interactions that I'm curious if I understand completely.

If I am using Zara, Renegade Recruiter and take control of a creature from their hand, will the "Return that creature to its owner's hand at the beginning of the next end step" follow the creature unconditionally? If I use Role Reversal and trade the creature from Zara (c1) with another opponent's creature (c2), will c1 return to the opponent's hand while I maintain control of c2? or will Role Reversal override Zara's condition?

Additionally, I know people often use Bazaar Trader to take control of creatures taken with "until end of turn effects" such as Act of Treason. Will this interaction still work with Zara? Bazaar Trader's rules text says it overrides temporary effects, but I'm confused on whether or not it would override the return to hand?

Thanks! "up to" text is always sneaky for me and I forget I cannot target. Thanks for the help!

Thanks for the response! Thought I found something cool in my deck. Turns out I just cheated.

Follow up question, when I target gravecrawler and he becomes an illegal target, does the ability fizzle or can I still draw?

On my board, I had a Mikaeus, the Unhallowed, Gravecrawler, and Yawgmoth, Thran Physician.

I use Yawgmoth's ability by paying 1 life, sacrificing the Gravecrawler, and the ability to put the ability "Put a -1/-1 counter on up to one target creature and draw a card." on the stack. When the Gravecrawler dies, Mikaeus triggers and returns the Gravecrawler to the battlefield with a +1/+1 counter. Can I place that -1/-1 counter on the Gravecrawler? Or would it no longer be a legal target because it left the battlefield and came back and I would need to choose a target prior to this?

I ended up using this as draw, and later on as a win with Blood Artist, but now I'm questioning if I made an illegal play.

Thank you for the clarification!

If I have K'rrik, Son of Yawgmoth on the battlefield and I am trying to cast a spell such as Bolas' Citadel, could I pay 3 of the black mana with 6 life, then cast a spell such as Culling the Weak to sacrifice K'rrik and use that mana to pay for the remainder of the Citadel? This doesn't make too much sense to me but someone mentioned to me it was possible. I know there are things such as LED which is exploitable because you pay costs after the spell is already on the stack. So is this possible, and if yes, why?

Thanks for the clarification!

Based on my research, it looks like this question has been beaten to death but with the release of Apex Devastator there's one question I still have.

Let's say I cast Apex Devastator with Imoti, Celebrant of Bounty on the field. 5 Cascade triggers go on the stack. The first trigger reveals some 8CMC spell in my deck. Would that spell's cascade (provided by Imoti) go on the stack after the remaining 4 cascade triggers resolved, or would it then be placed on top of the other 4? I think my confusion comes from the formatting of Apex Devastator's text. I know a single block of text is a single ability and can't be responded part way through. However, cascade states in the rules text that each one triggers separately. This leads me to believe that the 8CMC spell would go on the stack prior to the others resolving and you trigger each of the "strings" of triggers of the 5 cascades 1 at a time.

I'm fairly sure my line of thinking is correct, but I wanted to double check.

Thanks. 500 explains the question. I understand the change of phases and steps. The question was specifically pertaining to after end of turn triggers resolve.

I see in the linked thread that you are responding before starting the next phase. In my example the end phase has already begun which is why I was confused if players ever had a instance to react. Thanks for you help.
