We present a theorem that shows that all useful protocols for magic state distillation output
states with a fidelity that is upper-bounded by those generated by a much smaller class of
protocols. This reduced class consists of the protocols where multiple copies of a state are
projected onto a stabilizer codespace and the logical qubit is then decoded.
