Whenever you cast a spell, target opponent draws a card. Put a +1/+1 counter on target creature. It gains flying until end of turn. If this is the second time this ability has resolved this turn, you draw two cards.
Cast as many spells as possible each turn to repeatedly trigger Bumbleflower, stacking +1/+1 counters and flying onto your team while drawing two extra cards every second cast. You lean on cheap cantrips, free spells, and cost reducers to chain triggers, then close with an evasive counter-pumped threat or a wide flying board. The opponent draws are a downside you manage by ending games fast.
Lower your curve with free and one-mana cantrips (Mishra's Bauble, Gut Shot, ritual-backed casts) so you reliably hit the second trigger every turn. Add cost reducers and extra-cast enablers plus punisher pieces like Underworld Dreams to weaponize opponent draws into damage. Top end with protection (Heroic Intervention, Teferi's Protection) and a Helm of the Host or Isochron Scepter loop to multiply triggers toward a deterministic finish.
