master day 2 maul nightfall

Mulligan for Dusk Raider and/or low cost nightfall like Gloaming Wisp and Nocturnal Creeper Teacher of Humility is always good too against control try to get Jennev Merchant or Maul on curve
against aggro try to get Crystallize out of your market and get a nice board you want to play Crystallize then use that and the next turn to kill them with your board
Cykalis, the Burning Sand is good for getting rid of sites cough Howling Peak cough or just as decent damage
if you get berserk on Cykalis, the Burning Sand you can use to berserk and hit for 10 face damage without risking it dying
Equivocate can be great removal for big life steal or just annoying units such as Sandstorm Titan and Rizahn, Greatbow Master or even Vara, Vengeance-Seeker and Azindel, Revealed
Winter's Grasp is basically a Permafrost since it will always be night if you play your cards right
in most match ups you wanna use maul as a finisher but don't be afraid to play it if you can kill them in the next couple turns or if they just have a lot of cards in hand so it does as much damage as possible if you have any questions just ask i stream most days
