• Type: Treasure
• Cost: 5
• Effect: +3 Coin. This turn, when you gain a card costing 3 or 4, +1 Buy.

Treasure card with a +1 Buy trigger. Cost 5 +3 Coin (Gold-tier coin one cost cheaper) plus +1 Buy chained on each 3-4-cost gain.

Key strength: chain-buying. +3 Coin → buy Silver/Workshop → +1 Buy → another buy. 3-4 buys per turn standard.

Reliable +3 Coin in Buy phase, no Action consumed.

A-tier. On Allies tables, "above-Gold" priority. Core of economy axis.

Mid-game buy at 5 coins. 1-2 copies sufficient. 3+ excess but possible.

Mid-game: every turn for +3 Coin and chain buys. Easy Province threshold.

End-game: Galleria's +1 Buy enables Province + Duchy double-buys.

Galleria + Silver/Copper gainers: Buy cheap card → +1 Buy chain.

Galleria + Workshop/Artisan: Gain cost-4 Workshop → +1 Buy.

Galleria + Sycophant/Liaison: Cheap Favor cards → +1 Buy chain.

Galleria + Bridge: Bridge (cost 4) + +1 Buy multipliers.

Galleria + Merchant Guild: Coin token accumulation.

• Workshop/Artisan: Cost-4 chain.
• Silver/Copper: Cheap-card chain.
• Bridge: +1 Buy + cost reduction explosion.
• Liaison cards (Allies): Cost 2-3 chains.
• Throne Room/King's Court: Doubled Galleria.

• No cost-3/4 kingdom cards: Chain hard to maintain.
• Pre-thinned decks late game: Few buys needed.
• No trasher: Coppers crowd hand.
• Multi-player: Faster pile-out.

"Cost 3-4 gain" includes Workshop-gained, not just bought. Workshop + Galleria classic combo.

Galleria + Throne Room: +6 Coin, but +1 Buy trigger fires once per gain (each gain triggers).

Galleria-BM: Silver / Silver / Galleria → Galleria → Province. Very strong BM.

Second Galleria: Yes for economy + chain power.

Multi-player: Self-only effect, no opponent interaction.
