King 7c serves as our primary aggressor with his powerful 8,000 Power Rush attack
The other Commands (save for Silumgar's) all have dopey options you never really want much in multiplayer, Commander, or casual gaming, like gaining four life, preventing damage from a spell, or turning off life gain for a moment
The card is particularly useful in Yu-Gi-Oh Duel Links where it's part of a combo to combine it with Secret Pass to the Treasures to allow it to attack directly, and Union Attack to boost its ATK power tremendously while you control 2 other decently high-ATK Monsters (which won't nullify the restriction on Secret Pass to the Treasures being able to only use its effect on Monsters with 1000 or less ATK)
Here are all of its abilities: First Strike, Lifelink Ascend At the beginning of your end step, if you gained life this turn, create a 1/1 white Cat creature token
Getting FREE Vampire tokens each time you cast a Vampire is amazing, as you can tap them to use cards like New Blood or Captivating Vampire, sacrifice them to Indulgent Aristocrat, or just buff them into real threats with Vampire lords like Rakish Heir
Garruk's Uprising gives Trample to all our creatures and helps us draw more cards constantly
