When Kari Zev realized exactly whom she had rescued, she gave Baral a choice that was no choice at all: help her fight or be thrown overboard
Dragons of Tarkir gave us five newcomers (Dragonlord Silumgar, Dragonlord Atarka, etc.), Core Set 2019 gave us retrains of the originals (Arcades, the Strategist, Nicol Bolas, the Ravager), Strixhaven added five more as the namesakes of the different schools (Tanazir Quandrix, Beledros Witherbloom, etc.), and the five metal dragons from Baldur's Gate were also given the double creature type (Ancient Bronze Dragon, Ancient Copper Dragon, etc.)
During each of your turns, you may play up to one permanent card of each permanent type from your graveyard
Even if that didn't come with unblockability, that would still be a deal we're considering
