I am fairly certain your spell finishes resolving when the repeated process exiles no cards and therefore can no longer repeat. The instruction "repeat if this is true" is false (not the non-land part, but the "last card exiled" part, as no cards were exiled), and therefore the spell ends.

assuming there is at least one non-land card in your library when you cast it though, there is a last card exiled, and it's not a land.

Exactly, it'll keep exiling cards until there 0 cards left in your library. Then, on the next iteration of the "repeat this process" it'll exile no cards and the process will end.

The "last card exiled" is referring to the card you exiled on the last of the three exile instructions you just performed, not "the card most recently exiled, whenever that happened to be". If there is no third card, the process ends.

I have a slightly convoluted one.

I control a Meandering Towershell and a Clever Impersonator copying the Towershell. My opponent controlls a Colossus of Akros (It's Pacified or something). I attack with my two turtles, exiling them. During my next declare attackers step, the turtle and the impersonator enter the battlefield attacking. I can't copy my towershell with the impersonator because they enter the battlefield at the same time, so I copy my opponent's colossus this time.

1) Is this how this situation happens?
2) If a creature with defender enters the battlefield attacking, does it still attack or does defender cancel it out?

1) Not quite. You're right about Clever Impersonator not being able to copy something that's entering the battlefield simultaneously with it, but in this case, Meandering Towershell sets up a delayed triggered ability, so those will both trigger at once, go on the stack in the order you choose, and then resolve one at a time. If you put Clever Impersonator's delayed trigger on the stack first, then it will enter the battlefield second and you will be able to copy the Towershell. However, you might still want to copy the Colossus, because...

2) Defender prevents you from declaring an attacker, but it doesn't inherently prevent the creature from being in the "attacking" state, so if you do somehow put a defender onto the battlefield attacking, it will continue through combat like any other attacking creature.

What effects cause simultaneous ETB? I thought you could always order them. What if Brago, King Eternal flickered them?

Cards like Brago, King Eternal, Sudden Disappearance, and even See the Unwritten can all cause multiple permanents to enter the battlefield simultaneously. There is no order, so Clones and Auras won't be able to copy/attach to the other permanents.

This is why Warp World puts enchantments onto the battlefield last.

Dumb corner case curiosity!

What happens if I cast Aura Barbs when my opponent controls a Baleful Eidolon bestowed onto a 3/3 creature?

it deals 2 damage to your opponent, then 2 damage to the 3/3, killing it and letting the Eidolon be a creature. what do you expect to happen?

Wouldn't the Aura not have deathtouch itself until it becomes a creature, though?

From a direct reading of the helper text, I think Auras can have deathtouch! Like spells can (now) have Lifelink.

why would that be the case? how would the game determine which parts of its rules text to ignore in which situations? there's nothing banning auras from having deathtouch, they just usually don't.

It just feels logical that a card with Bestow doesn't actually have its own attribute, but rather Bestows it upon the enchanted creature.

From an MtG rules sense, then yeah, the Aura has deathtouch. There's no reason why it shouldn't because it's printed right on there and doesn't specify that it only applies when the card is a creature.

That doesn't make it "feel" right, though. You know, because of the meaning of "Bestow".

Damn semantics.

That.

by the way, on rereading that, I think that the lack of conveyed tone may have made my question sound harsher that it was intended, it was meant to be an honest inquiry as to what step of the process had led to the question.

Hi I´m new in this forum and I like to ask some questions about rules, how does it work here? is there some rules or I could just ask?

Thanks

You can just ask.

Thanks.

So, if in a multiplayer game some player reanimate a creature from other graveyard (not his graveyard) and later this creature dies, the creature card goes to the graveyard of the original owner or is exiled?

Same situation but instead of the creature dies, the player which stole the creature lose the game, so the creature goes to the owner graveyard or is exiled?

Could you please help me with the rule for each case. Thanks

1) In general, it should go to its owner's graveyard.


2) The creature actually goes back to whoever previously controlled it.
