Took the deck to Standard Showdown at my LGS, here is how it did.
Match 1 - Against Mardu Vehicles (0-2)
Game 1: Didn't draw ramp cards, he curved out perfectly to take it quickly.
Game 2: Flooded out, another perfect curve out by him to take the match. It
wasn't close at all, and he barely knew that I was even playing dinosaurs.
Match 2 - B/R Aggro (2-0)
Game 1: Deck did what it should, got Ghalta, Primal Hunger out on turn 4. He
used his Unlicensed Disintegration on my Drover of the Mighty so he
ran out before he could set up.
Game 2: He was cut on black sources and all my creatures were too big for red
removal.
Match 3 - W/U Token Embalm (0-2)
Game 1: Missed lethal because I forgot about Hashep Oasis, to which I am very
sad about. Also haven't played against this deck much, so I wasn't sure
what to kill first.
Game 2: He used Ixalan's Binding and Fumigate to kill all my stuff, then got
two Annointed Procession out to gain a ludicrous amount of life. Sad
day.
Match 4 - Mono Red (1-2)
Game 1: Soul-Scar Mage + Goblin Chainwhirler is a dumb combo, which
promptly made all my dudes small. Wasn't able to build a defense.
Game 2: Sideboarded pretty hard, was able to Ixalan's Binding a Soul-Scar Mage and win, since I was actually able to have stuff stay on the board.
Game 3: Too many lands yet again, dead by turn 4.
So, 1-4 is pretty bad. But considering it's the first tourny in the new meta, I won't give up yet. I'm thinking about adding Shalai, Voice of Plenty in the board, and possibly cutting the Beneath the Sands for something like Gift of Paradise, which will at least help in red match ups. I think the deck is there, and it'll be much better after Soul-Scar Mage rotates.
