Bilbo, Thief in the Night

Two abilities that reinforce each other, which is what makes the build interesting. The static cost reduction only applies to spells cast from somewhere other than your hand: graveyard, exile, the top of your library, wherever. On its own that discount asks for a deck already built to break the "cast from hand" assumption, which is a narrow ask. The attack trigger closes the loop by manufacturing those casts itself, letting you replay an artifact, instant, or sorcery straight out of the yard whenever the 2/2 swings. The two halves stack: the graveyard cast triggered by the attack is itself a spell cast from somewhere other than your hand, so the discount applies to it. What keeps the recursion from spiraling is the exile clause: instants and sorceries cast this way don't return to the graveyard to be looped again, so each spell is a one-shot rather than an engine you can drain a game with. Artifacts get no such restriction, which quietly tilts the design toward permanent value over spellslinging. The body is small and the discount is conditional, so this is not a card that does anything the turn it lands; it wants a graveyard already worth raiding and enough attack steps to raid it. As a translation of the character into mechanics, the theft framing lands: an unassuming figure who wins by taking things that aren't in his hand and getting away clean.
