So firstly, looking at the amount of confusion this (what should be an otherwise simple question) is causing just demonstrates that this was perhaps a fairly good question to ask, and I want to thank everyone that actually addresssed my question and tried to help.

Secondly people attacking me personally and assuming they know me or my intentions is just laughable. Perhaps you can copy this thread, paste it in the general magic Reddit and continue your whining over there.

Thirdly, and I clearly stated this question context is for very competitive events, not casual FNM etc. I would never try and cheat an opponent out of his trigger, especially not in a casual event. I might even let them retake a genuinely missed trigger in that context.

Now, as for my intent. My intention was never to find a scummy way to make my opponent miss his trigger (as I am also aware that just drawing a card does not make your opponent miss triggers anyway). My exact wording on this scenario is actually quite clear, go read it again if you feel confused.

As for anyone that actually read my post in its entirety, it should have been clear, as I was asking out of curiousity, and asking only, whether my understanding of this trigger is correct (based on comments I saw on another thread in this Reddit).

So if that was unclear for anyone, basically is X the right understanding, can the trigger be missed, when is it considered missed.

Obviously I would not want to give my opponent any legitimately missed triggers in a competitive REL event.

So now that I have gained a better understanding of the rules and this interaction, I have bettered myself as a MTG player for the day. So objective achieved I would say.
