Knowledge Seeker (TLA)

Creature — Fox Spirit

Vigilance Whenever you draw your second card each turn, put a +1/+1 counter on this creature. When this creature dies, create a Clue token. (It's an artifact with "{2}, Sacrifice this token: Draw a card.")

Niche card draw engine for blue tempo and prowess decks. Knowledge Seeker rewards the draw-heavy strategies that already want to be casting spells, but the payoff is slow—a single +1/+1 counter per turn cycle—and the creature dies easily without evasion or protection. The Clue token on death adds some value, but not enough to justify the slot over more efficient threats or dedicated draw engines in competitive formats.
