Agent Maria Hill
Teamwork is the mechanic asking creatures to tap in concert, and most contributors are content to be a body that helps pay a bill. This one turns that transaction into an engine: every time she taps to fund a teamwork cost, she grows and refills your hand, so the act of helping the team is also the act of building her into a threat. That reframes the cost from a tax into an investment. A one-mana 2/1 that has to survive combat and untap to be worth anything is fragile on paper, but the design leans into that fragility as a clock: the more teamwork you generate, the faster she outgrows the removal that would have answered the base body, and the card advantage compounds while she does it. The tension is that she only pays off if you have real teamwork density to draw on, so she is less a standalone beater than a payoff that rewards committing to the cooperative subtheme rather than dabbling in it. Note the trigger fires on tapping to pay the cost, not on activating it yourself, which makes her a beneficiary of the whole board's cooperation rather than a self-contained loop. Built for the aggressive white shell that wants to flood the board and turn a wide, coordinated attack into cards, she is the piece that keeps the fuel coming after the initial rush would otherwise sputter.
