Elvish Clancaller

The lord is the familiar half; the tutor is the trick. As a tribal anthem it does the standard work, pumping the rest of your Elves and joining the long line of lords that quietly beg to be drawn in bunches. The activated ability is the answer to that begging: for a hefty tax and a tap, it goes and gets another copy of itself straight onto the battlefield, so the first one you resolve doubles as a way to find the next. That turns a late-game glut of Elf mana into extra anthems without spending a card, which is the rare thing here. Most lords leave you hoping the missing copies come off the top on their own; this one folds that hope into an ability. The price is deliberately steep for a one-drop's worth of stats, and it self-limits: every search thins the deck of the card's own copies, so the engine winds down as it fires and eventually finds nothing at all. How much the button matters depends entirely on how many copies the deck is even allowed to run, which is why the same six-mana ability reads as a real engine in some contexts and near-dead text in others. The static line, meanwhile, works in every one of them.
