Character Background

K-9, Mark I is a low-cost, tempo-leaning support piece that reads like a defensive autopilot for legendary decks: while untapped it passively grants other legendaries ward {1}, shutting down single-target removal, and its tap ability can occasionally punch through blockers to finish a commander or enable a combo. Best used in a “legendary matters” build or a Doctor + companion commander shell (you can have two commanders if the other is the Doctor), K-9 excels at preserving value and enabling evasive damage rather than being a primary attacker. Deckbuilding tip: include cheap, evasive legendary finishers and protection staples (Swiftfoot Boots or Lightning Greaves) so K-9’s ward and unblockable activation compound; consider untap synergies like Seedborn Muse or Voltaic Key to keep K-9 available for ward while still using its tap effect when needed. Play it as a sticky blue utility threat that buys your big legends time and occasionally converts that protection into lethal reach.
