This question does not show any research effort. The first Google result for "prosperity mtg" has a ruling that says "10/4/2004 If both players run out of cards during this effect, the game is a draw." – RainboltRainbolt Feb 14 at 21:06Feb 14 at 21:06
The response I got was this:
I realize that now, but thanks for pointing out my stupidity and yours or lack there of, SENPAI – ericeric Feb 14 at 23:57Feb 14 at 23:57
For those who may not know, referring to someone as senpai in this way is a form of sarcastic admiration. That sarcasm, plus a jab about someone's stupidity, makes up the entirety of the comment. Comments really don't get any less constructive than this.
I flagged the comment as "Not Constructive", but the flag was declined. Was raising a flag the wrong thing to do? Did I raise the wrong type of flag (something I've been known to do in the past)?
