Modern Horizons contains a lot of cards that enable all kinds of sweet combos. In this article, I will describe 10 such combos that either go infinite or win the game right away. Some are close to competitive. Most of them are questionable. But all of them are fun to consider in Modern.

Infinite Modern Horizons Combos

1. Planebound Accomplice combo

Planebound AccompliceChandra, Torch of DefianceChandra, Bold Pyromancer - Foil - Planeswalker Deck ExclusiveCloudstone Curio

By repeatedly sneaking and bouncing different Chandras, you can deal infinite damage. It’s a four-card combo that is vulnerable to both Lightning Bolt and Nature’s Claim, so it doesn’t have competitive chops. But it’s a fun option, and there are various other planeswalkers like Koth of the Hammer that work as well.

2. Urza, Lord High Artificer combo

Urza, Lord High ArtificerSword of the MeekThopter Foundry

By repeatedly tapping and sacrificing Sword of the Meek, you can make infinite Thopters. (Just imagine the Servo in the video is a Thopter.) Thanks to Urza, those Thopters can be transformed into infinite mana and the ability to play your entire deck!

The Thopter/Sword combo has been around in Modern before and has found some competitive success. However, you’re paying one mana per life and Thopter token, which is too slow to race unfair combo decks. Thanks to Urza, you can now win on the spot, which could make a big difference.

Another way to go infinite with Urza is to combine him with Biomancer’s Familiar and Deadeye Navigator. By paying the blink cost with the newly created token every time, you can blink Urza as often as you like.

3. Farmstead Gleaner combo

Farmstead GleanerGrand Architect

By repeatedly tapping and untapping Farmstead Gleaner for mana, you get an infinitely large creature. You can add Fling to the combo for infinite damage or Training Grounds for infinite mana.

Grand Architect enables various other combos as well. Most notably, it can generate infinite mana with Pili-Pala. But Farmstead Gleaner can kill by itself, and it adds some redundancy for Grand Architect combo decks.

4. Morophon combo

Fist of SunsMorophon, the BoundlessStormfront Riders

Morophon plus Fist of Suns allow you to cast creatures of a chosen type for free. This means that you can repeatedly bounce Stormfront Riders to go infinite. You can keep bouncing Kessig Malcontents along the way for infinite damage, but Kessig Malcontents can be replaced by many other Humans.

5. Squirrel Nest combo

Intruder AlarmDryad ArborSquirrel Nest

If you set up a way where an Intruder Alarm trigger can untap the land enchanted with Squirrel Nest, then you can make infinite Squirrels. You can add Impact Tremors for infinite damage.

If you want to build a deck around this combo, then there’s plenty of redundancy. You can use Treetop Village instead of Dryad Arbor, and you can replace Squirrel Nest with Presence of Gond. Even without a creature land, Squirrel Nest on a Forest along with an Arbor Elf and an Intruder Alarm also goes infinite.

6. Ayula combo

Arcane AdaptationAyula, Queen Among BearsAnimation Module

This combo is not even close to competitive, but any time a card says “whenever,” I get interested. Going infinite with Ayula was a challenge, as it required a way to turn all Servos into Bears and a way to get one mana from Animation Module from every newly created Bear. But Mass Hysteria and Cryptolith Rite worked for that. In any case, I had fun setting up a combo where literal Grizzly Bears sets off a chain.

7. Altar of Dementia combo

Renegade RallierKaya's GhostformAltar of Dementia

Altar of Dementia is made for combos. If you have Kaya’s Ghostform in the graveyard and cast Renegade Rallier with revolt, then you can bring back Kaya’s Ghostform from the graveyard, sacrifice the creature to mill the opponent, bring everything back, and loop. The result is infinite mills. Similar combos were possible before, but Altar of Dementia unlocks redundancy. We can now run 8 copies of each combo element:

8. Vesperlark combo

VesperlarkPhantasmal ImageAltar of Dementia

Vesperlark and Altar of Dementia goes infinite with Body Double, Felidar Guardian, or Phantasmal Image. Since Phantasmal Image costs only two mana, it seems to be the best option. You just need to make sure that Vesperlark stays in play so that you can keep copying it with Phantasmal Image, which can then repeatedly return itself.

9. Yawgmoth combo

Yawgmoth, Thran PhysicianGeralf's MessengerGeralf's Messenger

If a creature has a +1/+1 counter and a -1/-1 counter, then both are removed as a state-based action. This means that Yawgmoth can go infinite with two undying creatures, until you run out of life or cards. Blood Artist can help offset the life loss.

You can also set up combos by combining Yawgmoth with Hapatra, Vizier of Poisons and Nest of Scarabs.

10. Ayula’s Influence combo

Ayula's InfluenceBeck // CallDakmor Salvage

This combo is somewhat reminiscent of Seismic Assault / Swans of Bryn Argoll. The difference is that you are making Bear tokens. Every Bear draws a card, which will be Dakmor Salvage if you keep dredging. Eventually you run out of cards, but you can use Emrakul to reshuffle if you really want to go infinite.

I found all these 10 combos enjoyable, but there are plenty of other combo possibilities with Modern Horizons. What’s your favorite?
