This is a classic ramp deck with a very solid late game. At its core, green mana provides a way to accelerate in
One curious aspect of the deck is the inclusion of
Jegantha, the Wellspring

This is the most widely applicable companion. The reason, however, is rather prosaic. It's just easiest to add Jegantha to your deck and call it a day. What's particularly boring about it is the fact that it does not add anything to the games—it's just going to be a 5/5 creature. But then the question is why not. Why not play a free 5/5, which can bail you out in some games? For whatever it's worth, it cannot be killed with

This is an example of a deck where Jegantha just fits. However, there could be versions which do not support it, for example if you run

A monoblue deck using a red-green companion? Yes please. It is of course castable in the deck thanks to

Jegantha is arguably best utilized here. It's a creature like everywhere else, but this deck wins by tapping and untapping a mana producer repeatedly, and Jegantha, while not the best, certainly qualifies. On top you're adding the fact that it's an additional card in hand when you pay the initial three mana. Why does that matter? The deck loots through its hand pretty aggressively with the namesake
Kaheera, the Orphanguard

While I highly doubt you can make a functional Cat, Nightmare, Dinosaur, or Beast tribal deck in Modern, Elementals have been pretty strong. You can incorporate Kaheera there, and it actually plays a meaningful role.

Keruga, the Macrosage
Bad news for Keruga lovers. I've scoured the results and there is nothing to be found. I am afraid there is nothing to suggest even as a reference here.

The big issue is that
Lutri, the Spellchaser

The hottest companion on the list. It's the reason why some players prefer to keep the companion mechanic legal—to be able to play Lutri. It makes your whole spell suite one-ofs, which is clearly a disadvantage. The restriction thankfully does not apply to the mana base. For that handicap you're getting a 3/2 flash creature that can copy any of your instants or sorceries. The consensus, if I can call it that, shows that its best home is a control deck. There is one list that I played and streamed for Cardmarket some time back. I have to say that the deck was super fun and dynamic. Due to all the one-ofs, each game is different and unique in its own way. In addition, your opponents cannot play around anything because … your hand could contain almost any card imaginable!
However, when you look at the actual list, you'll notice that it's a collection of the best cards in the format. It's not a random assortment of cards just for the sake of it—they are all super playable, powerful spells.

Obosh, the Preypiercer

The most aggressive companion. Its restriction is rather interesting—caring about the mana cost as even or odd. In practice, it simply means that your deck should not contain any zeros or twos. Most games will play out without Obosh becoming relevant. However, when it does come into play, the opponent has to fear all the burn spells as they gain a ton of mileage.

This deck sits at the middle point between aggro and midrange. It can have some aggressive starts but can also grind a while.

Another midrange strategy that abuses

Finally, here's a true aggro deck that puts immense pressure on the opponent. While you have to keep containing each threat posed, you also have to have a plan for that Obosh, which may come down and turn various small spells into big problems.
Umori, the Collector

Another companion that currently sees no play at all. On the surface it seems like
The best fit for Umori instead proves to be Enchantress, where even the creatures are enchantments. But one needs to go all the way back to August of last year to find an example among published results.

Yorion, Sky Nomad

The most predictable companion remains a cornerstone of Modern. It's now the strongest one by a country mile. Take your midrange or control deck, add twenty cards, and Bob's your uncle. Most likely you'll have some permanents with enter-the-battlefield effects to take extra advantage of Yorion's blinking. Not much to add here—except an example list of which you've probably seen a million already.
