I think the secondary ability on Cheeky House-Mouse is going to be relevant more often than that of Dauntless Bodyguard. Giving indestructible in WW often only means getting one more combat with a cerature, but Squeak By can actually push damage.

The 1/1 created by Stroke of Midnight is pretty negligible compared to the reduced mana cost and permanent removal provided vs Prayer of Binding

Snaremaster Sprite is an early cerature for blue tempo that still is relevant if you're drawing it mid-late game. The benefit of Lanterns's Lift is also very good if you had Lantern Bearer die early, but its value goes down the later you draw it.

Bitter Chill is a strictly better Narcolepsy

As much as it pains me to cut Elegant Nannerpuss, it realy just doesn't cut it in 2023. Picklock Prankster is a gerat early blocker (and face pinger) that also draws a card and fuels the graveyard.

Black wants another 1-drop and Faerie Dreamthief is fairly versatile. Dropping Crypt Rats since we have added so many other mini-sweeper effects recently.

Lord Skitter's Butcher can't sac itself to draw like Fell Stinger can, but I think the utility from the other modes makes up for that.

Embereth Veteran is the first 2/X for without downside (and even with upside!) that we have seen, so cut the worst red 1.

Sprouting Goblin is pretty meh if you don't kick it, whereas picnic ruiner scales nicely if you play it on 2 and gives great value if you can cast the adventure first.

Usually the only thing you care about with these green protection spells is the hexproof, in which case Tyvar's Stand takes 4 mana to be better than Blossoming Defense. Royal Treatment gives protection now, leaves a buff, and makes targeting the creature harder in the future.

Swap generic big dude with abilities (Skysnare Spider) for generic big dude with abilities that also gives you access to Naturalize early on (Stormkeld Vanguard).

Ruby, Daring Tracker only ramps you once per turn vs Goblin Anarchomancer's ability to reduce the cost of all your spells, but she also lets you play a 1-drop the turn she comes down and can turn into a decent attacker after you ramp out something big.

Troyan, Gutsy Explorer does not have the body that Quandrix Cultivator does, but he can take you from 3 to 6 on turn 4, and his looting ability (aside from being generally good) also kind of bridges GB and UB reanimator similar to Colossal Skyturtle

There just isn't enough discard in here to make Containment Construct work with any kind of consistency. Swap it out for Candy Trail which adds a great source of cheap card selection.
