Rose Tyler

Time counters usually mark a delay: you suspend a spell, count down, and the payoff comes later. This design flips that clock into a resource. The Bad Wolf trigger scans your suspended spells and any other permanent carrying a time counter, then dumps that many time counters onto a body that grows with each one. The result is a self-amplifying loop where the things you were passively waiting on (suspended spells ticking down, permanents parked under time counters) become fuel for an attacker that keeps outrunning its own count. What makes this notable is that it retrofits a mechanic built entirely around patience into an aggressive engine: the more you delay, the harder Rose swings, and the delayed cards still resolve on schedule. She is a two-mana white creature that scales off a counter type white almost never touches, which pushes the deckbuilding toward blue and red suspend cards and older time-counter oddities that had no shared home before. The Doctor's companion tag is the frame that legitimizes all of it, letting the counter engine sit alongside a partnered commander that can supply and count off the same time counters. It is an unusual thing to ask a color as forward-facing as white to reward waiting, and the tension between the aggressive body and the slow-cook engine feeding it is the whole design.
