An archetype that has been around since the beginning, continuously adapting and improving through the history of Magic. This is all-in aggro - AKA "Stompy". You cast big, dumb, under-costed creatures (that probably should have never been printed) and attack. I love "Big Green" because it brings out the kid in me. I get to cast giant monsters and attack my opponent's stuff! It is not a nuanced build, there are no complicated combos, but it is fun. Let's take a look.
When you are building in mono-green, one of the things you can take advantage of is being "deep" in the color. This is true for all mono-colored decks, but green seems to more frequently find some of its "cost" by requiring two, three or four green mana to cast a spell. Making a spell harder to cast in two or three color builds reduces the frequency of the spell and allows Wizards to push its stats. Stompy uses this restriction to its advantage. Keep an eye out or these cards when curating your deck over time.
The makeup of a mono-green aggro deck is fairly simple. It has a high percentage of creature cards with a few support spells that typically pump the power and toughness of your creatures. I run ten support cards with the balance of my build as creatures (twenty-nine in total). My full list is available if you want to use it as a starting point, but here are a few of its "must include" all-stars....
Dungrove Elder is amazing in this deck. It comes into play as at least a 3/3 with Hexproof and because his power and toughness scale according to the number of forests you have in play his top end potential is huge. The Elder is always a relevant play and something your opponent will need to counter or throw a chump blocker at every attack phase.
There was a day when a vanilla 2/1 for one mana was a slam-dunk to include in aggressive decks. I'm looking at you Savannah Lions! Now take that card and tack on an ability that completely neuters Snapcaster Mage, shrinks a Tarmogoyf and stops Dredge. Wow! This card is a Modern All-Star and is seen in a lot of sideboards for its ability alone, but its aggressive creature stats allow us to maindeck this card in Stompy.
One of the few non-creature cards that is a must in the build, Vines of Vastwood is a great combat trick for two green mana, but even more importantly you can use it to "counter" a spell being played on your creatures by the opponent. It's a super versatile card and worth four slots in the deck.
Far from a "must have", but I love playing this card in my green stompy build. Nobody sees the Groundbreaker coming - its three green cost keeps it out of most decks, but when it hits it hits hard. The green Ball Lightning will either swing the game heavily in your favor or eat one of your opponent's kill or counter spells. It is extra tough to stop when you are holding a Vines of Vastwood.
This little unassuming ghost is really annoying if you are staring at it from the other side of the table. 2/1 for two mana is not very aggressive, but the fact that it comes back after death as a 3/2 is just brutal. The Geist makes combat math a nightmare for your opponent since they have to think a turn ahead to the next combat before they kill this creature. Another "four of" include for Stompy.
So a word about "pimping" this deck. One of the things I personally enjoy about Magic, is the collecting aspect of the game. I enjoy seeking out rare versions of cards that I play and adding those printings to my favorite decks. For me, a big draw of this deck is the availability of full art cards for many of the includes. Stompy isn't exactly complex and the cards are pretty simple, so the lack of text makes full-art cards shine. I even run twenty-one John Avon full art forests. When you see my copy in play the deck is a work of art. I only wish I could find two of the full art Groundbreakers....
This is another cheap entry point into the Modern format if you are just starting out or returning to the game. Buying everything outright will set you back about $100.00 and you can probably trade for most of this on the cheap. It's a fun deck and will hold its own at Friday Night Magic while still being friendly enough for the kitchen table. If I could only have one deck this would probably be it as it checks off most of the things I personally love about the game. Enjoy the deck!
