Oracle Text

Card Details
Mana CostSet
Character Background
K-9, Mark I is a charmingly efficient support piece for a legendary-centered tempo or value deck, especially in Doctor Who Commander shells where the “Doctor’s companion” text opens up dual-commander options. At just {U}, it comes down early to start protecting your board: while untapped, it grants your other legendary creatures ward {1}, which quietly taxes removal and forces opponents to spend extra mana or wait for a better window. That makes K-9 particularly strong alongside a board of sticky legends, planeswalker-like legendary creatures, or commanders you want to keep on the table. His activated ability then turns offense into inevitability, letting a key legendary creature become unblockable for {1}{U} and a tap, which is ideal for pushing commander damage, enabling combat triggers, or slipping through a combo piece carrying equipment. Pair him with untap effects or vigilance to maximize both protection and evasion.
