Osseous Exhale 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
As an additional cost to cast this spell, you may behold a Dragon. (You may choose a Dragon you control or reveal a Dragon card from your hand.) Osseous Exhale deals 5 damage to target attacking or blocking creature. If a Dragon was beheld, you gain 2 life.
Complete guide
Osseous Exhale is a versatile white instant that punishes aggressive plays while rewarding your dedication to the Dragon tribe. By revealing a Dragon or pointing to one on your battlefield, you can turn a defensive strike into a significant life swing.
Beholding the Dragon
Osseous Exhale features a 'behold' cost. As you cast the spell, you may choose to behold a Dragon by either revealing a Dragon card from your hand or choosing a Dragon permanent you control. This is an additional cost that happens at the moment of casting. If you choose to reveal a card from your hand, that card stays revealed until Osseous Exhale leaves the stack, providing information to your opponents.
Damage and Life Gain
The spell targets a creature currently in combat—either attacking or blocking. It deals 5 damage, which is enough to take down most mid-sized threats. If you successfully beheld a Dragon during the casting process, the spell also grants you 2 life upon resolution. Note that even if the beheld Dragon leaves the battlefield or changes zones before Osseous Exhale resolves, you will still gain the life because the 'beheld' condition was met during casting.
Common Pitfalls
A common mistake is trying to target a creature that isn't in combat. Osseous Exhale cannot hit a creature that is simply sitting on the board during the main phase. Additionally, remember that a card like Teeming Dragonstorm, while themed around Dragons, does not have the 'Dragon' subtype and cannot be used to behold. Only cards with 'Dragon' on their type line count.
When to Play It
This spell is best used during the Declare Attackers or Declare Blockers steps. Since it deals damage, it is less effective against creatures with Indestructible, but excellent for removing high-toughness blockers or threatening attackers while stabilizing your life total.
Interaction examples
If your opponent attacks with a massive creature, you can cast Osseous Exhale to deal 5 damage. If that isn't enough to destroy it, you could follow up with Swords to Plowshares to exile it. However, if you use Swords to Plowshares first, the creature is no longer on the battlefield to be targeted by Osseous Exhale, so the order matters significantly.
During your turn, if your opponent blocks your creature with a high-toughness wall, you cast Osseous Exhale and behold a Dragon to deal 5 damage. If the opponent responds with Path to Exile to remove your Dragon permanent, the behold requirement is already satisfied. Osseous Exhale will still deal its damage and you will still gain 2 life when it resolves.

How it works : Osseous Exhale
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
If an effect refers to a “[subtype] card,” it refers only to a card that has that subtype. For example, Teeming Dragonstorm is a card that cares about Dragons and features Dragons in its art, but it isn’t a Dragon card.
No other card is named in this ruling.
- #2· Wizards of the Coast
Effects that say “If a [quality] was beheld” only care if a card of that quality was revealed or a permanent you control of that quality was chosen. No matter what happens to that card or permanent after that, it was still beheld, and any additional effects that depend on that card or permanent being beheld will still happen.
No other card is named in this ruling.
- #3· Wizards of the Coast
If a cost to cast a spell includes revealing a card, that card remains revealed from the time the spell is announced until the time it leaves the stack.
No other card is named in this ruling.
- #4· Wizards of the Coast
If a card in your hand is already revealed (perhaps because it was revealed to pay a cost of a spell that’s still on the stack or due to the effect of a card like Telepathy), you may reveal it again to pay the cost of another spell or ability that requires you to reveal a card from your hand.
No other card is named in this ruling.
