Terrifying Alliance - Pauper 2017

This deck, Terrifying Alliance, is made up entirely of 35 Allies, and 25 lands.  The reason for that is that almost all of the allies in this deck get pumped when another ally enters the battlefield, such that while a single ally alone in this deck is not impressive, Terrifying Alliance has a tremendous amount of synergy that is hard to fight off due to the sheer number of ally creatures.  Likewise, the converted mana cost of most of these cards is good for playing against blue, as the lower the cmc of an ally, the more worthless a card like Counterspell, or even the white Journey to Nowhere becomes.
This is the 3rd and by far the best version of this deck, or at least the most competitive.
Most of the more recent allies are not used because they are not good cards.
Allies never got that popular in MTG, but this is a good deck, at least for pauper, and last I checked, all the cards in it cost only a few pennies.
The strategy is to play that cards that boost first, and then have them boosted again and again once other allies come into play.
It is also worthy of note that the abilities of many of these cards occur when they come into play, including themselves.  For instance when Ondu Cleric enters the battlefield, it, itself will gain a life.  Similarly, with the Oran-Rief Survalist; when the card enters the battlefield it becomes a 2/2, due to a +1/+1 counter it gives to itself, and if Ondu Cleric was in play you would gain 2 life because both Ondu Cleric, and Oran-Rief Survivalist are both allies.

Yeva, Nature's Herald - Guru of the Deathtouch Flash - CMDR

First of all, one of the great advantages of monogreen is mana ramping.  Aside from creature ramp there are other ways of amassing an army with this deck, the artifacts or enchantments; Aether Vial, Bequeathal, Sensei's Divining Top, Sol Ring, Elfhame Sanctuary, Bear Umbra, and Lure of Prey.  Many of these cards I consider staples to monogreen commander.  So, while there is only 35 lands there are many others to provide assistance.

Aside from ramping, Yeva provides more defense than your average monogreen deck with cards like Mortal Wound, Spider Umbra, Prey Upon, and Ulvenwald Tracker, and especially 13 creatures with deathtouch that Yeva can flash into play (Regeneration deathtouch combos work great, especially if the air has no flyers, especially using Bower Passage, Gravity Well, or Spidersilk Armor).

The major assault to win the game comes from using 4+ converted mana cost creatures that green is well known for, and secondly pumping up the dinks, tokens and 1/1 creatures, pumping deathtouch creatures is a great idea, in your army with cards like Blanchwood Armor, Eldrazi Conscription, Gigantifom, Gigantomancer, Creeperhulk, Overwhelming Stampede, and Overrun.  Token generators include One Dozen Eyes, Deranged Hermit, Hornet Queen, and Mitotic Slime.
