text: Normally, when a token is created by this ability, it will simply be a Mirror-Sigil Sergeant, so it’ll also have the token-creating ability. (See the other ruling for weird exceptions.) At the beginning of your next upkeep, if you still control the original Sergeant, the token copy, and a blue permanent, you’ll get two more token copies; the turn after that you’ll get four; then eight; and so on.
