it is regarding the interaction between Greenwarden of Murasa and Natural Order. Can i sac Greenwarden as an additional cost to cast Natural Order then get back the Natural Order when Green die or is it too early? thank you in advance.

so i was listening MtA (Magic the Amaturing) about Kaladesh Prerelease Primer with L3 Judge Rob. Rob said something curious in regard to Crewing Mechanic and the phase-shortcut "Begin Combat". he said that once the primary player say that, it is too late to crew the vehicle. it is on the 35:50 of the video if you want to check it out for context. correct me if i am wrong but i thought saying "begin combat" is to let the opponent has their last chance to do things at THE END of the main phase.

Sanction Draft. Player F has Sin Prodder out. On one turn he drew his cards normally. He obviously missed his trigger. I told F that he forgot his trigger. Both players reminded me not to say anything. Why not? I shouldn't point out miss play?

This might be a stupid question but I am curious. Can we use gopro in a Magic tournament? This came up when someone was cheating, the other player called the judge. Cheater friend was with him and back him up on what happen. Your thought?

How does Tragic Arrogance works? Do I have to declare what I do not want to sacrifice while casting it or when it resolve? Thx on advance.

When I cast Infinite Obliteration, do I name the creature card when I cast it or when it resolve. Thank you in advance.

I have Phophet of Kruprix and a sliver. My opponent has Domri. He used Domri 2nd ability targeting my sliver. I flashed in a Diffusion Sliver in response, does my opponent has to pay 2? Thank you in advance.

I am playing a Sliver deck with Prophet of Kruprix on the battlefield. An opponent play Domri and he used its fight ability targeting my sliver. I flashed in Diffusion Sliver. Does he need to pay 2 to not have the ability counter? Thx in advance
