Doctor's Companion

Doctor's Companion is a keyword ability specifically used in the Commander format. Doctor's Companion was introduced in the non-canon Doctor Who set and is a Partner variant.
==Description==
Each card with Doctor's companion is a legendary creature.
Rather than a single legendary creature card, you may designate two legendary creature cards as your Commander if one is a card with Doctor's companion and the other is the Doctor. Doctor's Companion only works with creatures whose creature types are exactly (and not anything in addition to) Time Lord Doctor. Each Doctor's Companion is monocolored (or colorless, for one Companion) in contrast to the two-colored Doctors.
Cards with Doctor's Companion depict the the Doctor's closest friends, who accompany them on their travels. Despite the aligned numbers (13 Doctors with 26 Doctor's Companions), not all Doctors have their official companions represented (neither the Sixth and Eighth Doctor have theirs), and not all recognized companions have Doctor's Companion (i.e. <c>River Song</c>, <c>Wilfred Mott</c>, <c>Rory Williams</c>).
==Rules==
==Rulings==
*"The Doctor" means a legendary Time Lord Doctor creature with no other creature types, i.e. one of the incarnations of the Doctor from the Doctor Who decks and not a legendary creature with changeling.
*If you choose to have two commanders, your deck must conform to their combined color identities. 
*During the game, the two commanders operate independently. For example, the "commander tax," the additional cost to cast a commander from the command zone, is tracked for each commander separately. 
*Similarly, commander damage dealt to player by each commander is tracked separately. 
*If a card refers to "your commander," it refers to both, although if it's trying to perform an action on your commander, like put it into your hand, you choose which one it's talking about.
*Although Doctor's companion is a new variant of the partner ability, the rules for partner have not otherwise changed. Notably, Time Lord Doctors and cards with Doctor's companion do not interact with cards which have another partner ability.
