Revisiting an old friend for today's Planeswalker Duel Deck, with a new flavorful spin on things! My introduction article is linked below for anyone just a tiny bit late to the party. (No worries, the more the merrier!) You can also check out my author page on the sidebar for PDDs #1 through #9.

Full disclosure: I was brewing this deck right around the time Ikoria came out. While I already had a few ideas for our Greathearted feline here, I found bonus inspiration mostly because one card in particular caught my eye: Frondland Felidar. This card showcases a sizable body that has an insane ability for your Vigilance creatures. And wait! Ajani gives all your troops Vigilance! Clearly, this was a match made in heaven.

Ikoria featured a pretty unique theme for Green/White in the set as "Humans+Nonhumans" teaming up, so I incorporated that cooperative concept as well.

Time to meet the team:

The Game Plan

To succeed with this deck, apply pressure early with the Human brigade, back them up with the Nonhuman squad late, and try to play offense and defense with Vigilance creatures. Our removal is not fantastic, but our creatures are, so the "Removal Through Combat" doctrine is in play here. Some of our Humans can get big; Shanna and Citadel Castellan can swell up under the right circumstances, and Hamlet Captain provides humanity with some extra confidence when it comes time to battle. Alert Heedbonder, combined with Ajani himself, can gain enough life to put the game out of reach of your opponents and doesn't even need to involve itself in combat to do so.

Not to be outdone, the non-humans in this deck are potent as well. Patagia Tiger can send some of its Human brethren to the air for a big chunk, and sticks around to serve as one of the deck's few flying options. Oakhame Ranger can ally with either humans or another human-adjacent ally, depending on which half is more convenient. Keeper of Fables can keep the cards flowing while also providing some beef (or whatever the cat version of beef is; you meat experts out there can holler at me on Twitter, and yes, I know what I said); and we'll do everything in our power to keep Honey Mammoth snacking on our opponent. Clearly it's hungry, for goodness' sake—I mean, look at it!

I admit, removal here is kinda blah, but Selesnya Charm is still one of my all time favorites, given its flexibility and low cost. Ulvenwald Mysteries maintains card flow and a bunch of Humans hanging around. Look to blow out a combat with Fight as One; this deck is primed to optimize that effect.

The Rares

As I mentioned before, this was the inspiration for the entire deck. A solid size for the rate, it attacks well, it blocks well, and it's a tapper that can turn your whole team into tappers. If you have this and Ajani in play, you'll be able to pretty easily contain most any board state. Definitely the Rare you want to see the most.

Elephants are my favorite animal. I'm still waiting for the perfect deck for Loxodon Hierarch, one of my favorite creatures of all time. But until I find my Huckleberry, The Venerated One is a great fit in a deck like this. Some of the early Humans (or tokens produced by Ulvenwald Mysteries or Oakhame Ranger's adventure) don't fight particularly well, so they might just sit there and clog up the board. Venerated Loxodon turns those dinky tokens into much more formidable combatants, and might not even cost you any mana to do so. If your game plan involves playing lots of creatures to the board, Venerated Loxodon will always be a welcome addition.

I didn't end up playing any Ikoria because I don't play online and was on COVID-19 lockdown at the time, but I can't imagine one loses many games with this King Kong. It mangles a creature when it comes down, disenchants when it swings (and it doesn't even have to connect!), and indestructibles by rebuying a guy or sacrificing a token to the cause. Back in the day, in order to fit in all of those abilities without a drawback, Kogla would probably need to cost something around 10 mana. At only a 6-drop, Kong here is something special. Long Live the King!

Flavorfully connected to Ajani, this earned its inclusion because Ajani the Greathearted happened to fight against Bolas in the War of the Spark, and Ajani's Last Stand reflects Ajani's previous (successful) encounter against the Dragon Tyrant on Alara. Remember that the token flies.

Unsung Hero

Green/White decks are often good at playing the board. They're the colors with the most creatures, and this combination typically lets you get the biggest bang for your buck. However, Green/White is also a color combination that generally struggles to get ahead on cards. If your Plan A of "Big Fat Monsters" goes awry, Plan B can often just be a blank sheet of paper and a large, quizzical frown.

Ulvenwald Mysteries lets you keep a little extra gas in the tank, and in this deck, those extra cards come with extra Humans as well. It's uncommon that a card advantage engine also adds to the board in an impactful way like Mysteries can, which makes this a solid addition to any kind of board heavy strategy.
