Summoning the unknown (Standard)

Ramp as much as possible to pay a big X for "Tilonnali's Sumonner".
And protect it by any mean.

Wanted to add Lifecrafter's Bestiary for the card drawing and a "kind of" mana sink, but I really think Vizier of the menagerie can do a better job with that and can even fix my mana.

Finally gowing for Cathartic Reunion as my draw engine. It also helps looting when my hand is full of lands and let me dump them in the graveyard to play them with Ramunap Excavator or exile them with Hostile Desert.

Having tested the deck against
BW Vampire (0-2), UB Pirate(2-1), UB Aggro (1-2) and URG Energy (2-0)
I'm thinking to remove B and get W in instead. Main raison being that the meta (where I play), is actually way more faster than I thought, so i'll add the white to gain a bit more control and better removal like Settle the Wreckage. But for now I'll try to add Star of extinction and Hour of Devastation.
Also, Hostile desert with Cathartic Reunion is really good, last one being even better when I have a Ramunap Excavator out.
Changes V2.0 : -3x Fatal Push, -3x Claim // Fame for +2x Star of extinction, +2x Hour of davastation, +1x Chandra, Torch of Defiance, +1x Ramunap Excavator

Finally decided to play Gruul. I took out the Ranging Raptors, they really didnt perform as much as I'd hoped. Changed my removal a bit since the idea of splashing W or B, i'm going with an mass removal approach with Sweltering suns, Hour of Devastation and Star of Extinction. I also tried really fast Ghirapur Orrery and it performed way higher than I expected, letting my empty my hand of lands and letting me ramp at the same time. I was afraid my opponnents would take advantage of the extra lands, but most deck are just not made with that extra land in mind, so I generally go faster then them, because I have more lands in the main and especially when Ramunap Excavator is out. The fact that I have a lot of mana helps me empty my hand really fast to get advantage of the "Draw 4".

-2 Ranging Raptors

Play-tested the deck a little this weekend at my local fnm, but didn't got that much time.
Main matches being against UW GPG, UB Control/The Scarab God and finally UB Pirates.

First match : UP Pirates / 2-1
My opponent was very aggro with buffed dude/flyers and control-ish with negates and essence scatter. I lost the first one, but out-ramped him the second match. Was heading for time on the third game but opponent scooped claiming my deck was better than his. I would have like to see the end result of that game but... That match also scared me that the dec kwould be too slow and not viable.

Second Match : UB Control/The Scarab God / 0-2
Basic UB control deck, my opponent swarmed me with counterspells until The scarab god hit the table, bringing back all my countered creatures. This matchup didnt take that long, since I got destroy. I'm pretty convinced this deck is gonna be my hardest matchup, which is the main reason i'm trying Prowling Serpopard and Doomfall in the sideboard. I also wanna give a shot to Silent gravestone, turning the reanimator side of The Scarab God and GPG, but i'm still scared of Abrade.

Third Match : UW GPG / 2-0
My opponent missed some land drop on the first game, making me so far ahead and finally outnumbered him. Second game was a bit harder, but a Wayward Swordtooth on t3 and Ghirapur Orrery on t4, made me empty my hand really fast and card advantage too big. I really love Ghirapur Orrery in that deck, and my opponent are rarelly more advantaged than me.

Finally decided to take back black in the deck. Main reason being Claim // Fame, that card is insane for the surprise kill and i'm adding doomfall in the side against Control decks.

I got bored of the Wayward Swordtooth, really don't think they are changing that much, especially since I've found the Ghirapur Orrery(s). Same for Vraska, Relic Seeker, she is value, but she just doesn't fit in the deck.
Finally changed some lands for desert one and trying to play with Hour of Promise.

I tested a bit on MTGO but it wasnt that great. I'll playtest this weekend and come back with some results!

Changes V4.0 :
-3 (SB) Naturalize
-2 (MB) Shefet Monitor
-1 (MB) Vraska, Relic Seeker
-2 (MB) Wayward Swordtooth
+1 (MB) Arch of Orazca
+2 (MB) Desert of the Fervent
+3 (MB) Desert of the Indomitable
+3 (MB) Gift of Paradise
+2 (MB) Hashep Oasis
+3 (MB) Hour of Promise
+3 (SB) Thrashing Brontodon

Here's what I got from this weekend:
Ghirapur Orrery is kinda bad actually, even worst if you compare it to a 5/5 for 3, like Wayward Swordtooth.
The Nissa, Vital Force in the main is so good! The ultimate is easy to get to and gives a huge advantage with this type of deck.
I also changed a bit the SB to adjust with the The Scarab God meta.

Added/removed cards:
-2 Ghirapur Orrery
-3 Gift of Paradise
-2 Heroic Intervention
+2 Blossoming Defense
+1 Nissa, Vital Force
+2 Wayward Swordtooth
-3 (SB) Doomfall
-2 (SB) Silent Gravestone
+4 (SB) Magma Spray
+3 (SB) Puncturing Blow

Changed amounts:
+2 (Main) -3 (SB) Abrade
+1 (SB) Prowling Serpopard
