Confessor

Odyssey built an entire block around the graveyard and the act of filling it, and this Cleric is the white voice in that conversation: a passive payoff that turns every discard at the table, yours or an opponent's, into a trickle of life. The trigger is symmetric in source but asymmetric in benefit; it does not care who pitched the card, only that someone discarded one. That makes it a quiet tax on the discard-heavy decks the set encouraged, the threshold engines and madness shells that wanted cards in the bin as a resource. Against a deck spending its hand to fuel flashback and recursion, a one-mana body that drips life off each of those discards is the kind of friction that stretches a race a few turns longer than the math suggests. The life is incremental and never game-ending, which is the point: the gain is priced to be a nuisance rather than a wall, a body you deploy early and then forget while it works. It belongs to the small family of creatures that punish a specific resource behavior rather than attacking the board, and within that family it answers the most flavorful loop the block had to offer.
