Howling Mine is the grandparent of them all, having seen the light of decks back in Alpha , and it does have an interesting catch that not all later iterations have: You can turn the hugs on and off, as long as you have ways to tap or untap the artifact as needed

It also might make the cut in some versions of Edgar Markov Vampire Tribal as some of the better Vampires in the deck happen to be Clerics (Vito, Thorn of the Dusk Rose), Wizards (Bloodline Necromancer), Warriors (Kalitas, Traitor of Ghet), and Rogues (Nighthawk Scavenger), though admittedly there aren't many per category so I wouldn't expect more than 1 to be on the battlefield when you want to cast Zagras, Thief of Heartbeats
