Hraesvelgr of the First Brood 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, vigilance, wardShiva's Aid — When Hraesvelgr enters and whenever you cast a noncreature spell, target creature gets +1/+0 until end of turn and can't be blocked this turn.
Complete guide
Hraesvelgr of the First Brood is a formidable Elder Dragon that brings both tactical evasion and defensive protection to your board. Through its Shiva's Aid ability, it transforms every noncreature spell you cast into a powerful momentum swing that guarantees your threats reach your opponent.
What It Does
Hraesvelgr of the First Brood is a 4/4 flyer with vigilance and ward {2}, making it difficult for opponents to remove and capable of attacking while staying back to block. Its signature ability, Shiva's Aid, triggers both when it enters the battlefield and whenever you cast a noncreature spell. Each trigger allows you to give a target creature +1/+0 and make it unblockable for the rest of the turn.
How It Resolves
When you cast a noncreature spell, the Shiva's Aid ability triggers and is put onto the stack on top of that spell. You choose the target creature at this time. The ability resolves first, granting the power bonus and unblockable status even if the original noncreature spell is countered or removed from the stack. Because the bonus lasts until the end of the turn, you can trigger this multiple times to buff different creatures or stack the power bonus on a single attacker.
Common Mistakes
A common error is trying to use Shiva's Aid after an opponent has already declared blockers. According to official rulings, once a creature has been blocked, giving it the 'can't be blocked' status will not cause it to become unblocked. To ensure your damage gets through, you must cast your noncreature spells or have Hraesvelgr enter the battlefield before the Declare Blockers step of the combat phase.
When to Play It
Hraesvelgr shines in decks with high noncreature spell counts, such as those featuring artifacts, enchantments, or planeswalkers. It serves as both a finisher and a support piece. If you have a large creature that lacks evasion, Hraesvelgr provides the perfect path to victory by ensuring that creature cannot be intercepted by your opponent's defenders.
Interaction examples
When Hraesvelgr of the First Brood enters the battlefield, its own ability triggers. You can target Hraesvelgr itself, making it a 5/4 unblockable creature for the turn. Since it has vigilance, it can attack for 5 unblockable damage and still be available to block during your opponent's next turn.
If you have Roaming Throne on the battlefield with 'Dragon' chosen as the creature type, Shiva's Aid will trigger an additional time. When you cast a noncreature spell, you will get two separate triggers, allowing you to make two different creatures unblockable or give one creature +2/+0 and unblockable status.
Note that casting Solemn Simulacrum will NOT trigger Shiva's Aid because it is a creature spell. Shiva's Aid only triggers on 'noncreature' spells. However, if Hraesvelgr enters the battlefield while Solemn Simulacrum is already out, you can use the entry trigger to make the Simulacrum unblockable to poke for extra damage.
