Alduin is included in purchase of the pre-made Alduin's Apocalypse deck, which costs 500 gold. The card also has a rare chance to be obtained from Heroes of Skyrim card packs, or can be soul-summoned using 1,200 soul gems.
As Alduin destroys all creatures on both sides when summoned, playing him is not recommended while ahead in creatures. However, if you are behind, the destruction effect and Alduin's huge stats will generate a massive momentum swing in your favor, compounded further by his ability to revive a dragon every turn. This can be particularly devastating if he revives a creature with a powerful Summon effect, such as Paarthurnax or Odahviing.
Alduin's main weakness is his prohibitively high magicka cost. As such, he should only be played in control decks with a number of Dragons. Endurance decks are generally best suited for summoning Alduin as they have many ways to accelerate their magicka growth. In general, however, Odahviing may be a more reliable and flexible option, as it does not destroy your own creatures when played and has a less extreme magicka cost.
- "Ziil gro dovah ulse" ("Ever-bound dragon spirit") – Upon being summoned
- "Daar lein los dii!" ("This world is mine!") – When attacking
- Alduin is the main antagonist of The Elder Scrolls V: Skyrim. He is also the Nordic God of Destruction according to Varieties of Faith in the Empire and Varieties of Faith: The Nords.
- Using Desperate Conjuring on Alduin has wildly varying results, depending on the amount of magicka spent to cast him. A high-cost Alduin may summon an 18/18 Ancient Giant or even another copy of Alduin
- Alduin was originally depicted with four legs on this card, unlike in Skyrim, where he has two like all other dragons. In a recent change (In time for the game's release on mobile platforms), Alduin received revised art, which now properly shows two legs.
- The alternate card art shows Alduin atop a tower, this is a reference to the quest "Unbound" in The Elder Scrolls V: Skyrim, where Alduin destroys the village of Helgen.
