Blazing Shoal just isn't very good. If you want to use it's ACC, you have to play with high CC cards, so if you don't draw it, they clog up your hand. You also need to play cheap creatures to use it ASAP, so you need to draw three cards (one of which is specific), and it doesn't win the game, and it can be stopped by a simple counterspell, or a blocker, or creature removal, etc.
It might as well have Haste. If you play it on a land you didn't play that turn then it doesn't have summoning sickness and can attack the turn you play it. The fact that it doesn't specifically have Haste will almost never come up.
The point is that, against T&N, all Blood Moon does is slow them down a little. They're still going to, inevitably, cast T&N against you. UG is simply not the type of deck that is going to win before T&N gets to it's 9 mana.
Obviously Quash isn't going to do alot against Titan himself. That's what Mana Leak and Hinder are for. Honestly, for UG, if you can Quash their T&Ns and just counter Titan/Mindslaver..you win. And it's not that hard..you draw infinitely more cards than they do, and have card selection, which they don't, as well.
One aspect of Blood Moon that I like (besides slowing them several turns) is that it stops Boseiju.
Actually what it looks like is Contagion which was an extremely playable and good tempo card for black control decks in its format.
You say that removing a card is too much of a cost, that Chrome Mox is better, that it is unplayable at it's regular cost, etc, but you have no data to back this up, just your opinion. All I am saying is that you should playtest the card and get data about it.
I would playtest Sickening Shoal before writing it off because I honestly think this deck can't possibly be Tier 1 without that card. It's unbelievable how much it improves the matchup against Affinity. It lets you control their early Ravager nuts draw while also dealing with later-game Plate-Nexi and killing DotV. You are always threatening it; they can't assume they're safe because of a 4th-turn tapout. You run many expensive cards that are useless in the early game to fuel it. It is very well costed when not played off its pitch cost.
You cannot play Chrome Mox in such an artifact-hate-heavy format and then write off Shoal just because "losing a card is bad." You need to play with it and see what it does. I think what it does is let you stabilize a turn earlier and threaten removal at any time without being subsceptible to artifact hate.
I would not be surprised if we see a few Moonfolk ninja-a la
Moonfolk Shinobi UU
Creature-Moonfolk Ninja
Flying
Ninjutsu-Return a land you control to your hand.
Whenever this deals damage to a player, all players return a land they control to their hand.
1/2
That's so broken. Turn one man, turn two WIN THE GAME!
Given how much Night of Soul's Betrayal deals with (Disciple, Nexus, can't play out any more Ravagers, Beacon, mana accel creatures, the entire WW deck...), I'm surprised I don't see more copies in your lists. Everyone's putting it in the Sideboard at best, I think it's a lot more worthwhile than that.

I beat everyone to the punch this time.
