And no, Dimir Midrange (a deck this is based on) is not meta in Standart in any way. The most straightforward wincon is Bitterbloom into Heraldic Banner or Bitterbloom into Arnyn into Withering Curse for massive drain. Against control decks - Kaito turn 3 needed to beat them trivially, make sure to sit on Spell Stutters always. For creature decks like Badger: Bitterbloom turn 2 is a must and either fly past with Heraldic Banner or turtle with Arnyn, removals should be saved for Trample like Frenzied Baloth and Ouroboroid, or just withering curse them turn 3 and then go in. Izzet is the hardest matchup and you basically have to hope to draw into removals or catch a bunch of otters and slickshot in withering curse. For reanimator: Lord Skitter is instant win or hope for no Cavern of Souls and spell stutter spiderman, or steal spiderman or formidable speaker with the bat
