When to buy, skip or ban
CalculatedAn average deck banks enough Spamtons for the Common Shadowheart (15) by its turn-2 shop, if it saves.
Its value per 10 Spamtons (0.7) is below the median for its rarity (2); take it when it fits your plan, skip it when a stronger offer is on the table.
Shadowheart boosts a whole team, so it's a strong ban target against decks built around it — a ban removes every rarity for both players.
