Slow Start is a Jeskai (white-blue-red) legendary/Avengers tempo-midrange deck built around curving out with iconic Marvel heroes and gaining value from their synergy.
Its plan is to develop a board of efficient legendary creatures, then pressure the opponent through combat, teamwork-style buffs, and incremental value. Cards like Rally of Wings suggest the deck can swing wide or set up a strong alpha strike, while the mix of evasive/flexible threats and support legends helps it keep attacking from multiple angles.
The deck wins by assembling a team of synergistic heroes, leveraging their individual abilities and anthem/combat support effects, then overwhelming the opponent with coordinated attacks rather than relying on a single combo finish.
