Standard Grixis Dragon by Corey Baumeister
I noticed Corey playing this interesting take on U/R Flash the other day. Instead of playing a lot of counterspells, Corey instead added a bunch of removal, perhaps expecting a lot of Rogues and Gruul.
I haven’t been super impressed with Valki in Standard so far because it feels like everyone is playing a ton of removal at the moment, but if you take your opponent’s Bonecrusher Giant or Lovestruck Beast on turn two, he can be very strong. One of the advantages of this deck is that you can also simply play him as Tibalt later in the game.
Thanks to all the Pathways, playing three colors these days is quite easy. As long as you don’t put too many double color costed cards in your deck, you should be fine. Another possible option is to splash white instead of black, which even gives you access to Raugrin Triome.
I like that Valki gives this deck a solid early play but also an interesting top-end. You have plenty of stuff to do early and in the mid game thanks to cards like Bonecrusher Giant and Brazen Borrower, but sometimes you just draw too many lands and you need something bigger if they deal with your Goldspan Dragon.
Can I see this as a tier 1 deck? Probably not, although any combination of Bonecrusher Giant, Goldspan Dragon and Shark Typhoon is going to be strong by default because of how good these cards are currently in the format.
