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.)
Many of the villains from the Final Fantasy series are represented by double-faced cards in this set, allowing them to transform into their final forms once you meet the appropriate conditions
That can happen via the evoke ability, a sacrifice outlet, or naturally in combat
For just UU (two blue mana), this card can counter any target spell, and give you colorless mana equal to that spells cost at the start of your next main phase
Well look no further, because Populate is the mechanic for you
Dozens of unique mechanics
