Syr Carah, the Bold

A cantrip engine strapped to a ping. The tap ability does trivial damage on its own, but every connection with a player is what matters: her own pings, and any instant or sorcery you control that hits a face. Each such connection, regardless of how much damage it deals, triggers once and exiles the top card of your library with permission to play it that turn. A 3-damage burn spell to the face is one trigger, not three, so the engine rewards the number of hits, not the size of them: a hand full of cheap spells that each land on a player becomes a chain where the first find leads to the next. The design's honesty lives in the phrase "to a player": creature removal does not feed the engine, only reach does, which is why she pushes a deck toward face-damage spells rather than tempo trades. Timing sharpens the constraint, since the exile grants play-this-turn access rather than an open-ended stash, so the cards you dig into are the ones you can immediately convert, not resources banked for later. She belongs to the red spellslinger tradition of payoffs that reward casting many cheap burn spells in a single window, but where most of those want prowess triggers or graveyard fuel, this one demands that damage keep landing on a face until the library runs thin.
