Okay, Spider-Man might not be the most popular Limited format of all time, but drafts are still firing and we now have enough data to know which cards should be pulling you into their colors. Here are the actual best commons and uncommons in each color.

White

Spectacular Tactics

Starting out with a flexible trick/removal spell. There's a lot of big dumb creatures in this set and getting rid of them for 2 mana is a great deal. If you're lucky enough to have your own big monster in play, Tactics is a great way of protecting it, too. What's not to love?

Spider-UK

Hey, I was right about one! Spider-UK is the running for worst card name of all time, but it's also in the running for best uncommon in its set, so lets call it a wash. While this does have a slightly lower win rate than the card above, because it's not as reliable, it is much more exciting when it sticks around. It plays out pretty much as I thought it would, an engine that dominates any game it gets to live through.

Blue

Mysterio's Phantasm

This innocuous looking 1/3 turned out to be way better than it looks. It chips in for a cheeky point of damage here and there, blocks most early game plays, and fills up your graveyard with resources. It just does a little bit of everything, and that turns out to be quite good in this set.

Spider-Byte, Web Warden

Man-o'-War that can hit more than just creatures is a good card. Who knew? My pick (Flying Octobot) is only 0.2% behind this in win rate, but sometimes the boring answer is the right one. If the Spectacular Tactics suggests that big monsters are important, Spider-Byte being able to bounce them for 3 mana agrees whole-heartedly.

Black

Venom's Hunger

Look, I picked between two removal spells for best common. My choice, Scorpion's Sting, isn't far behind this (0.6% win rate), but it turns out, again, that killing big threats on demand is a big deal in this set and Hunger just does that without having to risk getting into combat. You almost always have a villain, so this ends up being easier-to-cast Murder with a bonus.

The Spot's Portal

This is a weird card, right? It's not just me? Nothing about this feels Black except for the losing two life if you don't have a villain. Luckily for Black players, it feels like every creature they have is a villain, so in limited this is basically just a Murder. Oh, right, maybe it does make sense in Black after all. Amusingly, this also has the exact same win rate as its common counterpart.

Red

Wisecrack

Yikes. I wrote in my original article "Red commons don't seem all that exciting." I was more right than I knew, because Wisecrack comes in at C- level on 17lands, with a mediocre 54.3% win rate when drawn. That's the best red common! If we were being generous, we could put Spider Manifestation in this slot, but, based on the deck colour data, that is doing its best work in Green decks, not Red.

Raging Goblinoids

It doesn't get much better at uncommon, unfortunately. Goblinoids is a fine card but the best uncommon having a 56.5% win rate is not fine. Red has seemed weak from the start of the format, and the data bares this out; even its best cards are ordinary.

Green

Professional Wrestler

What's not ordinary is how many good Green cards there are. When you pick best commons and uncommons on 17lands, a sea of Green washes over you. Granted, they're mostly uncommons, but Favored Fighter isn't far behind with a 58.5% win rate. This is exactly the kind of big monster we've been talking about all article and the fact that it helps ramp you towards your next one means that even having it killed isn't the end of the world.

Terrific Team-Up

Another removal spell, what a shocker! It's not that much better than my guess (Wall Crawl), but it is better. Indeed, this is the best non-rare card in the set, and with the context we have established above, it's easy to see why: killing big stuff is a big deal in this format. Team-Up kills pretty much anything while also allowing you to maybe get in a couple of points of extra damage. The fact that this is an instant negates almost everything that makes bite and fight spells risky, while also providing the aforementioned upside if your opponent is tapped out during your turn.
