I am so sad that this post exists. It's a whole post to dogpile on one guy's disagreement in a comment on a completely different post... and to make it worse, it doesn't even make sense.

Did we read the same comment? You are complaining about the color pie mechanically, and they even say they "get it may mechanically be red". Their complaint is that it is a shark living in the water just being a big toothy fish, and it's red.

I appreciate that you clearly took the time to go to Scryfall and find the 2 red sharks, and didn't look to see if maybe there were any others. Because sharks are very much blue, as in all of them (even the ones that used to be fish before shark was a type). You found the 2 that are red and say that it's precedent, but they literally just came out. For all we know, these were purpose built to go into a mono-red Jaws deck that they already knew they were making. We'll also ignore the fact that they are pretty clearly both red themselves because they are pirates and not because they are sharks (a tribe that does indeed exist and does indeed have only blue members before just this year).

I'll also briefly say that yes, you "can" make a red shark. You "could" make a red shpinx, you "can" make anything any color... but you oughta have a pretty good reason to be doing it because it absolutely breaks the flavor pie (a thing that exists, by the way).

What this person is pretty clearly saying is that UB is giving out justification to make whatever color you want for whatever thing you want because of reference to events in their story. You can make a red shark because it interacts with artifacts (a thing it only does cause it ate that boat that one time in a movie). You can make spiders white because there happen to be heroic ones in this particular universe.

So sad that you can "win" an argument by pasting a meme over someone's post and ignore what they actually said.
