Playing Modern on a budget is easy these days, with so many strategies cheaper than ever before. It wasn't as straightforward back when Wizards of the Coast was less aggressive with reprints, and when Masters sets were not as common as they are now.

In those days, just one strategy served as the de facto gateway to Modern for new players.

Mono-Green Stompy used to be a popular budget option since it was fast, resilient, and affordable. Despite not being at the forefront of entry-level Modern, it continues to be an excellent choice since you can use existing Standard cards for the strategy.

Mono-Green Stompy plays a different approach compared to other mono-colored aggressive builds. Green aggression lies in big creatures with game-ending keywords such as trample, and uses instants to grow the power of those creatures. Over the last few years the strategy has gone through a couple of changes, since Standard is pushing the power level of newer cards—especially in the green slice of the color pie. The strategy remains accessible, and holds its own in local competitive environments.

Budget Mono-Green Stompy

Mono-Green Stompy is achievable on a budget since the strategy centers around commons, uncommons, and affordable rares.

Buy This Card! https://www.tcgplayer.com/product/191064/magic-modern-horizons-weather-the-storm

As you can see, Mono-Green Stompy runs recent Standard cards such as Pelt Collector and Ghalta, Primal Hunger. If you are coming from Standard, Mono-Green Stompy is an excellent starting point to give those old Standard cards a new lease of life. Previously, the strategy ran vanilla creatures such as Leatherback Baloth since it could easily meet the mana demands. Due to power creep over the last few years, we have strict upgrades in Steel Leaf Champion and Yorvo, Lord of Garenbrig, which are more compelling win conditions.

Even with all this power, you can struggle to close out the game since very few of your creatures come with trample. Running Rancor will mitigate this issue and offers a recursive way to trample through to victory. There is a +1/+1 counter subtheme as you are looking to grow your threats, and Avatar of the Resolute and Experiment One benefit from all the other strong creatures you play. You can run a couple of Dismember mainboard if you want direct options to remove your opponent's threats. Plus, Dismember lets you shrink your opponent's creatures to push through extra trample damage.

Rounding out the build is Aspect of Hydra and Vines of Vastwood which enable you to have explosive starts. Vines of Vastwood is the preferred combat trick since it offers extra power for an extra mana. You can run Blossoming Defense in a pinch since it also offers hexproof and damage output, and it lines up favorably if you intend to play the archetype in Pioneer.

Semi-Optimal Mono-Green Stompy

Although Stompy is a hyper-budget strategy, there are numerous ways to improve the build with interaction.

Maindeck

Sideboard

First you'll want to look at converting those basic Forests into Nurturing Peatland and Waterlogged Grove.

Throughout the late game, you can run out of action since you are a hyper-aggressive strategy. Running around five to six of these lands will ensure you have something to do at all points of the game. Sometimes, that extra draw can prove to be enough in the right circumstances. In this instance, I'm using the cheapest variant possible since you care about generating green mana. There is a case for running Nurturing Peatland since you have Dismember, and it opens up options such as Surgical Extraction in the future. Horizon Canopy is a suitable alternative if you already have them, but these remain pricy due to the prevalence of Heliod Company and Selesnya Titan in Modern.

Rhonas the Indomitable provides another trample outlet and often becomes a creature since your devotion to green is high. Shifting to the sideboard, Veil of Summer offers shelter against countermagic and disruption, while Force of Vigor answers tricky artifacts and enchantments while allowing you to tap out on your turn. As you are in Mono-Green, you can easily pay the alternative cost on Force of Vigor.

Optimal Mono-Green Stompy

When you're looking to optimize, adding a handful of high-end cards will aid the prolonged game plan.

Maindeck

The Great Henge is one of the most powerful additions to Mono-Green Stompy in some time. Rarely you'll cast this for the native nine mana, since your threats have decent base stats. Alongside the card draw and counters synergy, the life gain is relevant since Modern is in an aggressive phase, with Burn and Mono-Red Prowess seeing success. Due to its inherent power in Standard and Commander, The Great Henge commands a high price, but you can still play Mono-Green without the artifact if preferred.

Hexdrinker is another nod for the midrange and slower matchups. Granted, Hexdrinker is slower compared to Pelt Collector, but it makes a strong impression the longer the game progresses. Notably, Progenitus "protection from everything" clause is game-ending on its own. Again, it makes for a powerful topdeck since you can level it up multiple times in the same turn.

If you want to grind out further, Questing Beast could be an exciting addition at the top-end. Coming from Standard, Questing Beast is a hallmark of Pioneer Stompy. You don't want too many since you have a low land count, but running a couple instead of Ghalta, Primal Hunger could provide inevitability. Questing Beast lines up well against opposing planeswalkers in midrange or control matchups, which could make it an excellent addition in the right metagame. Thrun, the Last Troll is another decent option if you anticipate a control-heavy metagame since the Troll Shaman blanks removal and countermagic.

What About Kaldheim?

With the continuing Kaldheim previews, there are a handful of cards for consideration in Mono-Green Stompy.

Snakeskin Veil follows cards such as Vines of Vastwood and Blossoming Defense. What makes Snakeskin Veil a viable option is the potential counter synergy alongside Avatar of the Resolute and Yorvo, Lord of Garenbrig. Since the counter remains after the spell resolves, it makes for a better defensive spell against targeted removal. Often you can lose out on damage if you have to use either Vines of Vastwood or Blossoming Defense to protect your threat on your opponent's turn. Snakeskin Veil could mitigate the downside while still offering hexproof like its predecessors. You could run a couple of Snakeskin Veil to aid the counter subtheme, but it's essential to keep the set of Aspect of Hydra since this is the best pump spell in the strategy.

Old-Growth Troll is an exciting option in Mono-Green Stompy. With the number of basic Forests in Stompy, there isn't much of a downside to running the Troll. Like Treetop Village, you can trade resources for attackers as the game progresses. Plus, the Troll can blank hate such as Field of Ruin since you run a high density of basic Forests.

However, Old-Growth Troll is competing with Steel Leaf Champion for the three-mana spot, and Steel Leaf Champion is a key part of the strategy. There is potential to run a couple of copies of the Troll if you expect a removal-heavy metagame as it pairs well with Aspect of Hydra. It's likely to feature in Mono-Green Food in Standard, and possibly in Mono-Green Aggro in Pioneer too. It's one to keep an eye on, as it offers a unique ability on top of above-average stats.

Mono-Green Stompy remains an excellent budget option if you want to enter the format on the cheap. Green has become one of the most durable colors in Magic, and its new cards are translating well into every format from Pioneer to Vintage. If you're new to Modern, why not start with a classic?
