Cavalier of Gales

Blue's entry in the Cavalier cycle is built around a payoff most control decks would already run without a body attached to it. Its enter trigger is card selection dressed as card advantage: three cards deep, two returned in the order you choose, which nets one card while arranging your next two draws exactly how you want them. That ordering is the part that rewards anything reading the top of your library, and it means the trigger is never wasted even when your hand is full. The death trigger closes the loop by refusing to hand the opponent a clean two-for-one: instead of sitting in the graveyard as fuel or a reanimation target, the Cavalier shuffles back and grants two more looks into your deck. A 5/5 flier is a genuine clock, but the intent is a value engine you can afford to trade freely, since dying reloads the library rather than emptying the board of a threat you will never see again. The mana value is the tax that keeps a self-shuffling, hand-refilling flier honest: strip the death trigger's shuffle and you have an on-color threat, but the shuffle grants the card its permanence, making it an asset the opponent can never truly remove, and that permanence is what the top of the cost buys back. Where the other Cavaliers lean on aggression or reach, this one is the patient member of the family, engineered so that every point of interaction spent to answer it costs the opponent more than it costs you.
