This clever pairing relies on Malignus's unique power-setting ability, which dynamically scales its power and toughness to half of the highest life total among your opponents. Because its starting power is already massive against any healthy opponent, just a few rapid boosts quickly push it past the crucial thresholds. This is where Mayael's Aria comes in during your upkeep, steadily growing your creatures with +1/+1 counters while checking those power benchmarks to instantly hand you the win once Malignus reaches 20 power.
