Linvala, the Preserver

Both entry triggers only fire when you are behind, which makes this a six-mana Angel built to do the most for the player who needs it most. Fall behind on life and it hands you a flat five back; fall behind on board and it drops a 3/3 flier to help hold the ground. If you are ahead on both axes, you get a 5/5 flier and nothing else, which is the point. The catch is that neither reward scales: it is five life or one Angel token, full stop, regardless of how far underwater you are. Being down twenty life gains the same five as being down one, and facing five extra creatures makes the same single blocker as facing two. That fixed payoff puts it in a different lane from white's older comeback tools, most of which are wraths or removal that reset the opponent's board; this instead pads your own resources while leaving their side intact. The result is a card that is strongest exactly when you have already taken a beating and inert when you are winning: it wants to be drawn late in a grinding game where life totals swing and creature counts seesaw, and it sits dead in an opening hand against a slower deck. Built for attrition, where a single top-decked six-drop that refills both your life and your board can flip a turn that looked lost.
