Its particularly powerful in black aggro decks where you already have a board presence and can capitalize on the card draw
Card not found, on the other hand, is the basis for a deck in Modern (its namesake actually) and played in Legacy Storm decks (maybe Vintage as well, I dont know the format enough to say)
While it is the most fun and explosive thing our deck can do, we can also just power our a Torgaar, Famine Incarnate on Turn 3, follow it up with Rekindling Phoenix on Turn 4, and go with the beatdown plan, which makes Torgaar's Rite more of a solid midrange deck that can also just combo kill opponents on Turn 3 when things go right, which seems like a solid place to be in Historic
Love her, but she's broken in multiplayer and Commander once down with that final ability killing multiple stuff across multiple players and such
While the lands excite me the most, I know theres a lot more to come
