Kindred Summons

A tribal payoff that scales off the board you have already built, then multiplies it in a single burst. The mechanic is the mirror image of most tribal spells, which reward you for going wide by giving each creature a small bonus; this one asks how wide you already are and answers by digging that many hits deep, dropping every match straight onto the battlefield. That makes it a doubling effect in disguise: control four Elves and it fetches four more, and unlike a sorcery-speed toolbox it fires at instant speed, so you can hold it for an end step or ambush at the end of an opponent's turn. The friction is baked into the count. With one creature it is a seven-mana spell that finds a single body, so the card demands a committed, populated board before it does anything worth seven mana, and it fizzles into nothing if you control no creatures of the chosen type. The shuffle clause quietly matters too: whatever creatures you passed over on the way to your hits get buried back in, so it is not a way to dig for a specific card, only to convert quantity into more quantity. It belongs to the lineage of green's payoff-for-critical-mass cards, sitting closer to the explosive end than the incremental one, and it rewards the kind of deck that was already winning by having the most bodies in play.
