Pretty simplistic deck. It's a ramp deck, it mainly focuses on getting a ton of mana early game and has a ton of cards that appreciate getting +1/+1 counters as well as other cards that generate counters as added value. The strategy is pretty straight forward, go big and go wide.
Regarding the non-creatures there is some protection that can give counters to your creatures, especially the Kami of Whispered Hopes, at instant speed and give them hexproof or indestructible. White is pretty good at removing creatures, but it's also really good at protecting them, giving us a reliable way to escape boardwipes in the form of Unbreakable Formation although it does not get around exile, Farewell will still be a huge bitch for us, it also provides some absolute bangers like Virtue of Loyalty (and Ghalta and Mavren, but we'll get to that later). The Snakeskin Veil is ideal for protecting a mana dork, as it only costs 1 green and can therefore come out early enough that you get to tap that Kami for a good chunk of mana. The backbone of our value engine is Tribute to the World Tree which is an insane enchantment that basically turns our mana dorks into 3/3 beatsticks on entry and draws us cards whenever we play big creatures, there is no lost value here, even playing a turn 6 Llanowar Elves is good value, getting you a decent blocker for only one mana, another banger on that list is obviously Fight Rigging an accelerant that allows us to pump one of our creatures each turn and get a free spell once one of our creatures hits over 7 power, which can happen as soon as turn 4 or 5. Ram Through is mostly here to get rid of Sheoldred, the Apocalypse, but it's also a nice way to just finish your opponent at instant speed by just crashing one of your big tramplers into one of their creatures.
Now, the main attraction, here, are obviously going to be the creatures, the classic mana dorks, I personally choose to run 2 Llanowar Elves and 2 Elvish Mystic, even though running a full playset of either one of them amounts to exactly the same, it at least allows us to somewhat get around things like The End (in case the opponent REALLY hates ramp, I guess...), Unmoored Ego or Curse of Silence by having two different named cards that do exactly the same thing. Our best dork, by far, though, and the reason I built this deck the way it is, stacking counters and so on, is because of this card, right here, Kami of Whispered Hopes, not only does it ramp us insanely fast (I mean, not as fast as turn 1 ramp, but it can get crazy pretty quickly...), it also contributes to our strategy by increasing the number of counters we put on our creatures each time we do, not only is it good ramp, it's also good value, it is, however, very fragile, with only a body of 1/1, it'll very likely attract removal like a magnet, which is the reason why you're running protection in the first place, getting it to stick even for just one turn is already worth it, but the strategy here is obviously to have it stick around for as long as we can and possibly use it late game to beat the opponent with it. There are a couple of big haymakers in this deck, but the one I really want to focus on are the Gruff Triplets, now this card is absolutely INSANE, it makes three bodies for one card, and it buffs the remaining copies each time one of them gets removed, it also has trample and a pretty low cost of 6 for essentially three creatures. One of my personal favorites, as well, is Ghalta and Mavren, anything that makes more bodies is awesome in our deck, because of Tribute to the World Tree, mainly, it's also nice to have a way of getting some lifelink damage, especially with Sheoldred being a thing.
Manabase is pretty simple, it uses Nykthos, Shrine to Nyx to ramp us up, the landbase has been calcced so that you usually don't get mana-screwed, although nothing is 100% rng-proof, I took the liberty to use some of the creature lands, they're optionnal, though they do add an additional blocker or attacker that is really hard to remove.
Sideboard is very straight forward, we play white, so we run 4 leylines of sanctity, some more instants for protection and a couple more Ram Through, so feel free to balance them to your liking.
Edit : As explained in the comments, I swapped Ram Through for Get Lost and Unbreakable Formation for Guardian of Faith, further capitalizing on white as one of the best colors for control and protection, testing is still required, and acquiring the cards on arena will take me some time, although I will be testing it on paper format (since I do own most of these cards).
