Bloodline Bidding 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
Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays foror one mana of that creature's color.) Choose a creature type. Return all creature cards of the chosen type from your graveyard to the battlefield.
Complete guide
Bloodline Bidding is a powerful sorcery that can turn the tide of a match by resurrecting an entire army at once. By leveraging your existing board state with the Convoke ability, you can bypass its high mana cost to bring back your fallen tribal allies. This card serves as a devastating finisher for decks focused on specific creature types.
Mass Resurrection Through Unity
Bloodline Bidding allows you to choose any creature type and return every card of that type from your graveyard directly to the battlefield. The standout feature is Convoke, which lets you tap your untapped creatures to pay for the mana cost. Each creature you tap pays for one generic mana or one mana of that creature's color, meaning a large board of small creatures can effectively make this spell free.
Step-by-Step Resolution
First, you cast the spell by determining the total cost and tapping creatures or paying mana. When the spell resolves, you choose a creature type. It is important to note that you do not choose the type when you cast the spell, but only as it resolves. Once you make the choice, the cards are moved from the graveyard to the battlefield immediately. Players cannot respond between you choosing the type and the creatures entering the battlefield.
Common Pitfalls
A common mistake is trying to use the same creature for both a mana ability and Convoke; if you tap a creature for mana, it is no longer untapped to be used for Convoke. Additionally, remember that Convoke does not change the mana value of the spell, which remains 8. Finally, you can tap creatures with 'summoning sickness' for Convoke, as the ability does not use the tap symbol in its cost.
When to Cast Bloodline Bidding
The best time to cast this spell is after a board wipe or a series of trades that have left your graveyard full of a specific tribe. Because it is a sorcery, you will typically use it during your main phase to set up a lethal attack for the following turn, or to immediately regain board control if your opponent has exhausted their resources.
Interaction examples
Suppose your graveyard contains four Vampire cards. You cast Bloodline Bidding, tapping three black creatures you control to reduce the cost to five mana. As the spell resolves, you choose 'Vampire,' and all four cards are placed onto the battlefield simultaneously.
While Rise of the Dark Realms returns every creature from all graveyards for nine mana, Bloodline Bidding offers a more targeted approach for eight mana. With Convoke, Bloodline Bidding can often be cast much earlier in the game than Rise of the Dark Realms, provided you have a few creatures to tap.
Bloodline Bidding shares the 'Choose a creature type' mechanic with Kindred Dominance. If you have previously cleared the board with Kindred Dominance by choosing 'Dragons,' you can later use Bloodline Bidding to choose 'Dragons' again, returning any that were lost earlier in the game to an empty battlefield.

- #2· Wizards of the Coast

No other card is named in this ruling.
- #3· Wizards of the Coast
If a creature you control has a mana ability with
in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.
No other card is named in this ruling.
- #4· Wizards of the Coast
When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated. Convoke doesn't change a spell's mana cost or mana value.
No other card is named in this ruling.
- #5· Wizards of the Coast
You can tap any untapped creature you control to convoke a spell, even one you haven't controlled continuously since the beginning of your most recent turn.
No other card is named in this ruling.
