Just a gang of elves that like elves. Pretty simple and effective typal deck.
Llanowar Elves, Elvish Archdruid, Llanowar Loamspeaker, Llanowar Tribe, Priest of Titania are all mana dorks that are also just extra elves. We don't need this much mana but at a certain point all that matters is how much elf we have, and the hydras will soak up all the mana we can produce.
Nissa Revane and Wellwisher can gain us absurd amounts of life (we're not playing the card that Nissa can search up). This allows us to take a beating instead of having to chump block and lose our precious elves.
Jagged-Scar Archers is the only thing we have that can take out fliers and it gets absolutely massive in the late game.
Immaculate Magistrate turns little dorks into stompy beasts and is our main win condition.
Elvish Warmaster makes extra elf tokens, again to up our count because many of the best effects care how many elves we have.
Beast Whisperer draws cards -- we're often casting multiple creatures per turn and with multiple of these in play we're basically refilling our whole hand every time. This is definitely one of the best cards in the deck.
Collected Company because if you can play Coco, you do.
It's a simple mana base -- I tried a lower land count but if you don't curve out in the first four turns things can get really sketchy. Myriad Landscape helps us get lands out of the deck so we don't draw them later.
