Ancient Bronze Dragon turns combat damage into a large counter boost. After hitting a player, you roll a d20 and put that many +1/+1 counters on each of up to two targeted creatures. A high roll can create two enormous threats, while even a smaller result supplies lasting growth rather than a bonus that disappears at end of turn.
The Dragon can be one of the targets, helping the next attack become more dangerous. An evasive creature or one with trample is another useful recipient because it can turn the counters into damage more reliably. Branching Evolution and other counter support can increase the number placed, adding another layer to the payoff.
Targets are chosen for the ability that follows the roll, so you know the result before deciding where the counters go. Opponents can respond to that ability, making protection relevant if a chosen creature is central to your plan. Double strike can generate another roll when the Dragon connects in both combat damage steps.
Seven mana is a major investment in a creature that needs combat damage before producing counters. Haste, an open attack route, or a way to remove flying blockers can matter more than an additional counter multiplier. Green counter and Dragon decks can use the card as a large payoff, but should build for useful outcomes across the die's range. Two well-chosen recipients often make a modest roll more valuable than simply putting every available boost on the largest creature.
