This is a commander specific combo we can do. With the locust god and a locust out, Skullclamp reads: : "Draw 2 cards and make a locust." This is a pretty good effect on it's own, and should be used if you feel safe doing it. Combined with either of the altars, we can sacrifice a locust to pay the require mana cost to equip the Skullclamp, drawing more cards. Rinse and repeat to draw your whole deck, and do whatever you want.
To get to this combo, you can tutor for Skullclamp with Trinket Mage, and you can Fabricate for the any piece. Since there's two altars we have a higher chance of grabbing one of those. We can grab any of these pieces with Whir of Invention or Transmute Artifact (given you have an artifact to sacrifice to it), as well as Inventors' Fair.
What is nice about this combo is we don't care if there's something like Cursed Totem out, as we don't need to use the looting ability of our commander here.
This is a classic combo you see, where we imprint Dramatic Reversal onto Isochron Scepter. With from mana rocks, we can generate infinite colored mana. Something like Sol Ring + Mox Opal could do the trick, but basically mana rocks + Dramatic Scepter = good. With the infinite colored mana, we can then loot through our entire deck with our commander's ability and win the game like this.
A problem you might encounter is if there's some sort of Cursed Totem effect that is stopping us from being able to loot. A backup to this can be using Sensei's Divining Top to draw your entire deck instead. Just use use the Dramatic Reversal, then tap the top in response. Let the reversal resolve and tap the top again in response, and repeat this process to draw your whole deck and win with the infinite locusts. The best part is, the top doubles as good draw smoothing in the deck, so it's not a dead card otherwise.
Another backup with this if Sensei's Divining Top doesn't work for some reason is to Copy Artifact the scepter, imprinting Swan Song. This allows you to generate infinite swans by just targetting your own Swan Song over and over again, and untapping with the other scepter. I don't really recommend actively trying to go for this (it requires too many cards), and I've never really done it in a game, but it's there.
To grab Isochron Scepter, Fabricate can get it, as well as Whir of Invention or Transmute Artifact (though with the latter two, make sure you have Dramatic Reversal in hand). You can also grab it with Inventors' Fair. For Dramatic Reversal, we can use Spellseeker to search it out from our deck, as well as Merchant Scroll or Mystical Tutor. Muddle the Mixture grabs either of these cards, which is nice.
This is a simple way to loot through your deck if you have your commander out. Once you play him, he triggers a draw, creating an insect, and the loop continues. His ability is also a "may" so you can stop whenever you want (so you don't deck yourself out). This way you can draw your deck and swing with locusts, or drop some of the above combos. You can search for Sage of the Falls using Imperial Recruiter, which is nice. It's a good two card combo that should win you the game.
This is a cool combo you can do with TLG out. Once you play Dockside Extortionist, you make a ton of treasures (hopefully), and then sacrifice a locust and bounce it with Barrin's ability. Then you replay him, making more, and hopefully generate infinite mana so you can loot through your deck with our commander. After that you can play some of the other combos we have, or just swing out with locusts as usual. You can search for both creatures with Imperial Recruiter, but I recommend finding Barrin, Master Wizard first, then bouncing Imperial Recruiter and replaying him to find Dockside Extortionist.
This is a combo that doesn't really need our commander. By itself, Underworld Breach is a nice card to get some value, but combined with the above two other cards, you can mill out the table/get your combo pieces into the yard and win from there.
How this combo works is that you want to loop LED and Wheel of Fortune over and over again, exiling 6 cards in the process. You net 1 extra card in the yard, so be sure to try and exile lands and non-interaction while you are doing this. Eventually you can pick up your other win cons and try to win from there, or if you somehow have more cards in your deck than everyone else, just win via milling them out.
This also works with Windfall instead of Wheel of Fortune, but someone needs to have 6+ cards in hand. With Locust God out, you will generate a ton of tokens and can probably swing out, too. This is a pretty flexible combo.
You can grab Lion's Eye Diamond with Fabricate, Inventors' Fair, Transmute Artifact, Whir of Invention, or Trinket Mage. You can grab Wheel of Fortune or Windfall with Personal Tutor or Mystical Tutor. You can get Underworld Breach with Muddle the Mixture.
Wheels
Any of the wheels in this deck can enable you to win or just bog the opponent's down super hard. A wheel with Narset, Parter of Veils will leave the opponents with almost nothing, reminscient of Leovold. A wheel after Cyclonic Rift will leave your opponents in disarray as well.
