Ancient Copper Dragon turns combat damage to a player into a potentially large Treasure supply. After connecting, you roll a twenty-sided die and create that many Treasures. The result can fund more threats or a major second-main-phase play, but the mana arrives only after the Dragon successfully deals its combat damage.
Lightning Greaves or Swiftfoot Boots can give it haste, reducing the time opponents have to prepare before its first attack. Double strike can create a trigger in each combat damage step when the Dragon connects both times. Token doublers such as Anointed Procession increase the Treasure output, while Academy Manufactor can convert that creation into a broader collection of artifact tokens. The die roll still makes the baseline output variable.
Combat payoffs need a dependable route to the defending player. Check flying blockers, available removal, and effects that prevent damage before committing every resource to one attacker. Haste can reduce the delay between deploying a threat and using it, while Equipment can make an existing creature more relevant without requiring a second expensive threat to survive an entire turn cycle.
Flying helps the Dragon connect, but it is not unblockable. Keep removal or protection available when the first successful hit is important to the turn. The Treasures arrive from a triggered ability after damage, so their mana cannot be spent before that trigger resolves or assumed available when paying for earlier combat setup.
