Rationale

Berta is a 4cmc Simic legendary that self-grows via Increment (counters when you cast expensive spells), generates mana of any color whenever she gets counters (making her a pseudo-mana-engine), and converts mana into X/X Fractal tokens. Her counter-trigger produces mana without using the stack, enabling explosive turns where casting spells fuels more mana fuels bigger Fractals. Signature in +1/+1 counters shells and Simic big-mana strategies; slow to set up but self-reinforcing once rolling.

Learnings (3)

  • Berta's 'add one mana of any color' triggered ability is a mana ability (it doesn't target and it produces mana), so it doesn't use the stack and cannot be responded to — this makes her counter triggers extremely fast.

  • Increment checks power OR toughness (greater than either), so Berta's 1/4 body means any spell costing 5+ mana triggers the counter gain off her toughness until she grows large enough that power catches up.

  • Berta's X-cost Fractal ability combined with her own mana-generation trigger creates a self-reinforcing loop: putting counters on Berta via the activated ability generates mana that can be immediately reinvested into more X activations in the same turn.
