At the beginning of your upkeep, draw a card if you control the creature with the greatest toughness or tied for the greatest toughness.

Trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.) Other creatures you control have trample.

Flying Whenever Ancient Bronze Dragon deals combat damage to a player, roll a d20. When you do, put X +1/+1 counters on each of up to two target creatures, where X is the result.

Flying Whenever Ancient Copper Dragon deals combat damage to a player, roll a d20. You create a number of Treasure tokens equal to the result.
