Dracosaur Auxiliary 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, haste Whenever this creature attacks while saddled, it deals 2 damage to any target. Saddle 3 (Tap any number of other creatures you control with total power 3 or more: This Mount becomes saddled until end of turn. Saddle only as a sorcery.)
Complete guide
Dracosaur Auxiliary is a fearsome Dinosaur Dragon Mount that brings immediate pressure to the battlefield with flying and haste. While it is formidable on its own, it truly shines when paired with a crew, triggering powerful area-of-effect damage when saddled. This card is an excellent top-end threat for aggressive decks looking to close out games quickly.
What it Does
Dracosaur Auxiliary is a 6-mana creature with 5/5 stats, flying, and haste. Its primary unique mechanic is Saddle 3, which allows you to tap other creatures to empower it. If you attack with Dracosaur Auxiliary while it is saddled, it deals 2 damage to any target, which can be a player, a planeswalker, or a creature.
How it Resolves Step by Step
To use the saddle ability, you must act during your main phase while the stack is empty. First, you announce you are activating the Saddle 3 ability and tap untapped creatures you control with a combined power of 3 or more. Once the ability resolves, Dracosaur Auxiliary is considered 'saddled' until the end of the turn. When you subsequently declare it as an attacker, its triggered ability goes on the stack, allowing you to choose a target for the 2 damage.
Common Mistakes
A common error is trying to saddle Dracosaur Auxiliary after you have already declared it as an attacker; the creature must be saddled *before* the declare attackers step for the 2-damage trigger to fire. Additionally, remember that being 'saddled' is a status, not an ability. If a creature like Goldspan Dragon were to copy Dracosaur Auxiliary after the saddle ability resolved, the copy would not be saddled.
When to Play It
Because it has haste, Dracosaur Auxiliary is best played when you have creatures ready to tap for its saddle cost immediately. This allows you to deal 5 combat damage and 2 target damage the very turn it enters the battlefield, potentially removing a blocker or finishing off a weakened opponent.
Interaction examples
With Goldspan Dragon on the battlefield, you cast Dracosaur Auxiliary. During your main phase, you tap Goldspan Dragon (which has 4 power) to pay for the Saddle 3 cost of Dracosaur Auxiliary. You then attack with both. Goldspan Dragon triggers to create a Treasure, and Dracosaur Auxiliary triggers because it was saddled at the moment it was declared as an attacker, dealing 2 damage to any target.
You control Etali, Primal Storm. You cast Dracosaur Auxiliary and use its haste to attack immediately. Before moving to combat, you tap Etali (6 power) to saddle the Dracosaur. Upon attacking, both creatures' abilities trigger: Etali allows you to cast cards from libraries, and Dracosaur Auxiliary deals 2 damage to a target of your choice.
