Takeover counter

Takeover counters are a type of counter introduced in Doctor Who. They are used to track cards in exile for related effects.
==Description==
Takeover counters first appeared on <c>The Master, Formed Anew</c> in Doctor Who. They act as markers on the card exiled with it to allow it to become a copy of that creature. This allows for future copies of The Master, Formed Anew to become a copy of cards exiled by previous versions.
