Cantrip

Low-cost spells, almost always one mana, that draw a card while also smoothing the next draw via scry, surveil, or library look-and-rearrange. Opt scrys then draws; Preordain scrys two then draws; Serum Visions draws then scrys two; Ponder rearranges the top three and draws; Consider surveils then draws; Brainstorm draws three and tucks two back. Narrower subset of card_advantage.card_draw, restricted to the cheap self-replacing spells that effectively cost zero net cards. Distinct from card_advantage.scry, which only smooths without drawing, and from card_advantage.impulse_draw, which exiles cards to cast later rather than putting them into hand.
