Goldberry, River-Daughter

Gameplan

Goldberry is a mono-blue counter-manipulation engine: load counters onto cheap permanents, vacuum them onto Goldberry, then redistribute them where they matter while drawing a card each time. You build incremental card advantage and counter mass, then redeploy counters to win via a giant Walking Ballista, planeswalker ultimates, or counter-fueled creatures. Most turns you proliferate, shuffle counters, and dig deeper into your engine pieces.

Key Cards

• The Ozolith — Banks counters when creatures die and feeds Goldberry a reusable reservoir to redistribute.
• Inexorable Tide — Proliferates on every spell you cast, endlessly refueling counters for Goldberry to move and draw off of.
• Karn's Bastion — A land-based proliferate engine that keeps Goldberry's counter pool full without spending cards.
• Walking Ballista — A premier payoff—load it with counters via Goldberry to machine-gun the table.
• Astral Cornucopia — Stockpiles charge counters that Goldberry can shuffle into draws and payoffs while ramping you.
• Resourceful Defense — Protects your investment by relocating counters off doomed permanents, synergizing with Goldberry's whole plan.
• Power Conduit — Another counter-mover and untap-adjacent piece that lets you convert and recycle counters flexibly.

Upgrade Path

Lean hard into proliferate (Tezzeret's Gambit, Steady Progress, Contentious Plan, Flux Channeler) and counter doublers available in blue to multiply every move. Add untappers like Thousand-Year Elixir, Seedborn Muse, or Inspiring Statuary effects so Goldberry can move and draw multiple times per turn, and include protection (Lightning Greaves, Swiftfoot Boots) plus fast mana like Sol Ring and Mana Crypt. Tighten the win to a compact Walking Ballista or planeswalker-ultimate package so the engine actually closes games.
