I'll analyze Modern Affinity deck performance by the number of Springleaf Drums in the maindeck over the last 30 days.
Based on 482 Modern Affinity entries from the last 30 days, Springleaf Drum count shows interesting performance variation. The 1-copy configuration performed best with a 55.5% winrate (212-170 across 75 entries), followed closely by 0 and 4 copies both at 53.7%. The 2-copy build was most popular with 164 entries but posted only 50.8% winrate, while 3 copies underperformed at 49.4%.
The data suggests that running exactly 1 Springleaf Drum or committing fully to 4 copies yields better results than the middle-ground 2-3 copy splits. The 1-copy approach may provide flexibility without overloading on a potentially dead draw, while 4 copies maximizes consistency for builds designed around the mana acceleration.
