Martha Jones

Investigate is usually a slow-value keyword: you bank a Clue, you cash it later for a card, and the tempo cost of that sacrifice is the tax you pay for the draw. This design flips the tax into the payoff. Every Clue you crack does not just replace itself: it turns Martha Jones and one friend into unblockable attackers for the turn, which means the Clue engine and the combat engine are the same engine. Build a deck that generates Clues at volume and each sacrifice becomes a targeted evasion grant, stacking as many times as you can afford in a turn. That reframes the whole card. It is not a value creature that happens to draw you a card; it is a combat-damage enabler that funds itself with card advantage, and the Woman Who Walked the Earth trigger seeds the loop the moment she lands. The companion pairing widens the pool further: two commanders means more artifact and token synergies feeding the Clue count, and every one of those Clues is now a potential swing enabler rather than a dead artifact sitting on the battlefield. The 3/2 body is fragile on defense, which is the honest read on where the design wants her pointed: forward, cracking Clues to push connections through, not sitting back drawing cards.
