Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)

was around, mono-green was everywhere. Since then, the deck has suffered quite a bit. However, with a recent top 16 finish in a Magic Online Pioneer Challenge, perhaps we shouldn’t be overlooking this shell as much as we have been.
The Usual Suspects

The majority of the cards featured in this deck overlap with the core of the old mono-green Devotion shell. First and foremost, the deck wouldn’t be complete without
Elvish Mystic


−1: Untap target permanent.
or
Old-Growth Troll

When Old-Growth Troll dies, if it was a creature, return it to the battlefield. It's an Aura enchantment with enchant Forest you control and "Enchanted Forest has '{T}: Add {G}{G}' and '{1}, {T}, Sacrifice this land: Create a tapped 4/4 green Troll Warrior creature token with trample.'"
on turn two, setting up for a big follow-up.

are solid threats that put a lot of pressure on the opponent right off the bat. However, they do much more than just that. With Kiora in play, your burly three-drops become cantrips as well. With access to
Nykthos, Shrine to Nyx

{2}, {T}: Choose a color. Add an amount of mana of that color equal to your devotion to that color. (Your devotion to a color is the number of mana symbols of that color in the mana costs of permanents you control.)
, these three-drops immediately add three Devotion to help you cast big spells. In games where you play Troll or Polukranos turn two after playing an Elf turn one, your opponent now has to fear
Cavalier of Thorns

When this creature enters, reveal the top five cards of your library. Put a land card from among them onto the battlefield and the rest into your graveyard.
When this creature dies, you may exile it. If you do, put another target card from your graveyard on top of your library.
coming down the following turn thanks to Nykthos.
Part of what makes this green deck a pain is that removal isn’t exactly super effective against Troll or Cavalier. If you kill Troll, it becomes an Enchantment that not only ramps your opponent further, but adds three Devotion for Nykthos all the same. Cavalier is a monster that helps dig you towards Nykthos, and if you kill it, your opponent gets to make sure their next draw is a good one.
Additionally, Cavalier can mill copies of
Storm the Festival

Flashback {7}{G}{G}{G} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
, which is the ultimate Devotion payoff. Getting to put two potent cards into play is already good, but the fact that it has Flashback makes it incredible. Sure, it costs ten mana to Flashback, but this is surprisingly easy with Nykthos in the mix.

Where Things Differ

Where things get interesting is with the inclusion of Garnled Professor in the typical Karn slot. In old Devotion lists, Karn provided the deck with an infinite combo utilizing
The Chain Veil

{4}, {T}: For each planeswalker you control, you may activate one of its loyalty abilities once this turn as though none of its loyalty abilities have been activated this turn.
, the flip side of
Pestilent Cauldron

{1}, {T}: Each opponent mills cards equal to the amount of life you gained this turn.
{4}, {T}: Exile four target cards from a single graveyard. Draw a card.
, and looping Planeswalkers. With enough Devotion and multiple copies of Karn and Kiora between the battlefield and the graveyard, you could gain infinite life with via the flip side of Pestilent Cauldron. From there, the front side of Cauldron provided a way to deck your opponent, making winning trivial.
While this combo was a bit convoluted, it meant that the mono-green deck didn’t have to worry about winning via traditional combat. Karn also provided a lot of utility in different spots, letting you tutor for various cards depending on the situation and matchup. Without Karn, this deck turns to another intriguing toolbox-style card: Gnarled Professor.
Gnarled Professor is a big Creature in its own right, but its real power comes from its Learn ability. If you have a decent amount of Devotion, you can grab
Mascot Exhibition




While certainly weaker, Gnarled Professor helps provide a similar mix of options as well as a mana sink that could be used as a win condition. Unlike Karn, Gnarled Professor only requires a few sideboard slots to be utilized. As such, this deck uses playsets of

Strengths and Weaknesses

Between the size of the Creatures this deck plays and the value cards like Professor and Cavalier can generate, this deck has a decent gameplan against Izzet Phoenix. Azorius control, despite having access to counter magic, can struggle against the deck’s massive mana advantage if even a single payoff resolves. Midrange decks have historically struggled against value-oriented beaters like Troll and Cavalier, so adding Professor to the party has its benefits.
The main issue with this strategy is how poorly its position is against combo decks. Damping Sphere is obviously strong against Lotus Field, but the matchup can be tough without it. Not being able to combo yourself with Karn or grab
The Stone Brain

Speaking of which, the Abzan Amalia matchup is awful. This deck plays little interaction, and now having to rely on Creature combat against the deck’s life gain package means that your clock isn’t generally fast enough.
Also, while the midrange matchups are favorable, Rakdos midrange in particular is much less popular nowadays. This is largely due to the rise of Rakdos Vampires. Rakdos Vampires can present a

on turn three, which can be extremely hard for the Devotion deck to beat. In this sense, mono-green has pretty polarizing matchups in the current Pioneer metagame. If you’re a fan of this style of deck and don’t expect a ton of Amalia combo, mono-green Devotion is a reasonable choice, but it’s important to acknowledge its limitations.
