Goal of this deck is to get all of our creatures with power <1, such as Sekki, Seasons' Guide, Kalonian Hydra, Trostani's Summoner and Trostani Discordant to the graveyard, and return them on the battlefield with Vesperlark as early as turn 3.
To help us dig to our wincons, we have cards like Fauna Shaman, which is great in this deck, because not only does it get your big creatures to your grave, but it also fetches for Vesperlark. There´s also cards like Commune with the Gods, which works great in this deck, because it puts the creatures you need into your graveyard, and it also fetches for one of your 2 powerful enchantments in this deck. Eladamri's Call is there to fetch for our creatures that we need.
There are also 2x one drops Greenseeker and Llanowar Mentor, which help with getting our big creatures from our hand to our graveyards and at the same time fix our manabase.
Restoration Angel is great for protecting our important dudes as well as multiplying our army (by exiling Trostani's Summoner we get an additional trigger, when it comes to the battlefield from the exile. Same thing goes for Emphemerate.
To finish them off, there is Divine Visitation and Doubling Season, which both work really well with Sekki, Seasons' Guide, and of course Triumph of the Hordes, to pump up your little token army and finish the game on the spot.
Ideal game: T1: a simple land, no rush, T2: drop a Fauna Shaman, T3: discard any of your big dudes (ideally Trostani's Summoner) into your graveyard with Fauna Shaman, and tutor for Vesperlark, cast him for your remaining 2 mana (for it´s evoke cost) and bring Trostani's Summoner back to your battlefield with a bunch of tokens, T4: Triumph of the Hordes ftw

With some very helpful tips in the comments, I decided to change the deck a bit. I took out the enchantments, which realistically almost never hit the board, and swapped them for some great utility cards. I also took Triumph of the Hordes out, and put one in the sideabord vs life-gain decks. I basically stick to the original plan, which is to reanimate big things by turn 3 with Vesperlark, thus creating a wide board and then swinging in for the win. I've decided to add Seasoned Hallowblade to the party, because it help us get stuff into the graveyard without paying any mana or worrying about removal. I also added 3 Eldritch Evolution, because it's just far too powerful for this deck to not be included. The point is, by turn 3, you've (ideally) reanimated one of your wide board dudes (for example Trostani's Summoner ), however a turn later (turn 4), you have few creatures and a useless 1/1. That's when Eldritch Evolution comes in handy, because you get rid of your useless 1/1, and either go wider with another Summoner, or you buff your dudes with the one copy of Elesh Norn, Grand Cenobite.

Hello fellow reanimator enjoyers. Just hopped on here to update some things I've changed in this deck. First off, I decided to cut my playset of Llanowar Mentor, because I figured that replacing them with a playset of Greenseeker works much better for mana fixing, because I often times ended up with a llanowar elves token (from Llanowar Mentor ) on the board with no haste, when what I really needed was 1 more mana for another spell (example: T3 you have a greenseeker in play, you didn't hit your third land, you have both vesperlark and a big creature in hand. You discard the big creature with greenseeker (for one mana), thus getting the 3rd land you need for casting vesperlark for its evoke cost(for 2 mana). With mentor, you'd just be stuck with a small dude for you next turn). So that's why I made this change. Also, now I'm rocking 3 Seasoned Hallowblade because our manabase is fixed, and we need some things to help us get things into our graveyard, thats not easily removed. This card ensures both things. I ended up removing Restoration Angel from the deck completely, because it often times ended up being a dead card in my hand. We can realistically keep reanimating all game, and restoration angel wasn't any help, so yeah. I fixed some issues in the side-board, but for now, that's all I can say. The idea of the deck remains pretty much the same. Reanimate, go wide, and kick some ass.
17.5.2021: So I have tweaked the deck a bit again. First off, Commune with the Gods, as good as it is in this deck, ended up burrying our lands a lot of the times, so I had to replace it with 4 copies of Grapple with the Past. For now, it has been working really well. I decided to add 2x Eternal Witness, cause it's just a great utility card for the late game. You can get your vesperlark, eldritch evolution or a land back, if needed. I've also added two more copies of Deep Forest Hermit (making it a total of 3 copies). Unfortunatelly Elesh Norn, Grand Cenobite ended up being pretty useless in most of the games, and would just sit in my hand for no reason, so I've moved it to the sideboard vs creature based opponents. I also took some advice and went back to a full playset of Eldritch Evolution to hit our new addition, Iona, Shield of Emeria, as we moved our Elesh Norn, Grand Cenobite to the sideboard vs creature-based opponents. Iona is a freaking blast to play, because you basically lock your opponent on turn 4 in game one, which is sometimes the difference between winning and loosing a game. I also ended up going up a Fauna Shaman, making it a full playset, as it truly is a core card in this deck Instead. The rest stays pretty much the same. I tried making as competetive of a sideboard as I could. For obvious reasons, there are 2 copies of Damping Sphere for storm and tron match-ups, two Force of Vigor against blood moons, Stony Silence for the gravehate and kitchen match-ups.
I also changed the manabase a bit. One Gavony Township for the late game works really well with Kalonian Hydra. Once we have these two cards on the board and a little token army ready to bite our opponents, just pump all of our creatures and let them get bigger with each swing.
The initial idea remained the same, and I have to say this deck is just so much fun to play. It's also pretty decent in competetive league, so I'm really looking forward to testing it at my LGS.
Thanks to every one who upvoted or commented, I really do appreciate it. Great advices are always welcome:-) cheers
