Old Gnawbone is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
Flying Whenever a creature you control deals combat damage to a player, create that many Treasure tokens.
Complete guide
Old Gnawbone is a massive Legendary Dragon that turns every point of combat damage into immediate mana production. By rewarding your aggression with Treasure tokens, it ensures your board state accelerates just as quickly as your opponent's life total drops. Whether you are swinging with a single flyer or a massive army, this Dragon provides the fuel for your most expensive spells.
Wealth through Warfare
The core mechanic of Old Gnawbone is its triggered ability that triggers whenever a creature you control deals combat damage to a player. Unlike some abilities that only trigger for the creature itself, this Dragon watches your entire board. For every point of damage that successfully connects with an opponent's life total, you create one Treasure token. Because these are Treasure tokens, you can immediately tap and sacrifice them to add one mana of any color to your mana pool.
Step-by-Step Resolution
First, you must move to the combat phase and declare attackers. Once your creatures deal combat damage to a player, Old Gnawbone's ability triggers. If multiple creatures deal damage, the ability triggers separately for each creature that dealt damage to a player. As each trigger resolves, you count the amount of damage that specific creature dealt and create that many Treasure tokens. These tokens enter the battlefield untapped and ready to be used during your post-combat main phase or on your opponent's turn.
Important Timing and Limits
It is vital to remember that this ability only triggers on combat damage. Damage dealt via spells or 'fight' mechanics will not generate Treasure. Furthermore, the damage must be dealt to a player; hitting a Planeswalker or a Battle will not trigger the ability. If Old Gnawbone deals damage at the same time as other creatures, its ability will still see all of them and trigger accordingly, even if Old Gnawbone receives lethal damage during that same combat step.
Strategic Implementation
Old Gnawbone is best utilized in decks that can go 'wide' with many small creatures or 'tall' with one massive attacker. Since the Treasures are generated based on the amount of damage, increasing a creature's power directly increases your mana production. It serves as a perfect bridge to cast your game-ending spells or to maintain mana for protective counterspells after an all-out attack.
Interaction examples
You attack with Old Gnawbone, which has 7 power. Your opponent has no flyers to block. Old Gnawbone deals 7 combat damage to the player. The triggered ability resolves, and you create 7 Treasure tokens. You now have 7 additional mana available for your second main phase by sacrificing those tokens.
With Old Gnawbone on the field, you cast Craterhoof Behemoth. Your creatures gain trample and a massive power boost. Even if your opponent blocks, the trample damage that spills over to the player is counted as combat damage. If your creatures deal a combined 30 damage to the player, Old Gnawbone will create 30 Treasure tokens.
You have Old Gnawbone and ten 0/1 Plant tokens from Avenger of Zendikar. After growing your Plants with Landfall, you attack with all ten. If five Plants each deal 2 combat damage to the player, Old Gnawbone triggers five times, creating 2 Treasure tokens per trigger for a total of 10 Treasure tokens.
