Cantrips are inexpensive spells that replace themselves by drawing a card while providing another small effect, often card selection. They help decks operate more consistently without significantly reducing the number of cards left in hand. Notably, any card that has the text “draw a card” attached to it is also technically part of this group.
Some of the best cantrips are Ponder rearranging or shuffling the top of your library before drawing, Preordain combining scry with a draw, and Brainstorm temporarily putting three fresh cards into your hand.
