The deck uses Leonardo, the Balance and Michelangelo, the Heart together to build a wide board of creatures that grow through +1/+1 counters, leveraging Michelangelo's attack trigger to generate Food tokens that repeatedly fuel Leonardo's ability to spread counters across all creatures whenever a token enters. Counter-doublers like Corpsejack Menace accelerate the board's power level, while the deck attacks repeatedly to rack up counters and eventually overwhelms opponents with a massive, trample-and-lifelink-enabled alpha strike enabled by Leonardo's activated ability. Supporting spells provide token generation, board protection, and ways to convert the ever-growing creatures into an insurmountable combat advantage.
