Flight-Deck Coordinator

The end-step trigger keys off a board state most white go-wide decks are already producing for free: the natural residue of an attack step, when a pile of your creatures is sitting sideways. That makes the two life a reward for the plan you were running anyway rather than a tax you build toward. Because the condition checks tapped creatures broadly rather than attackers specifically, mana dorks, crew fodder, and creatures tapped by their own activated abilities all feed it just as well as bodies that swung in. The one thing that works against it is vigilance: a creature that stays untapped through combat no longer counts toward the threshold, so a deck leaning on this trigger wants its threats spending themselves each turn rather than holding back. As a body, a 3/3 for sits where a wide deck wants to be committing multiple threats anyway, and the lifegain quietly widens the margin against decks trying to race the same clock. This is a support piece, not a centerpiece: the trigger fires only on your end step and only asks for that pair of tapped bodies, so it does nothing the turn you have emptied the board and nothing in isolation. Its value is in the aggregate, an incremental drain on the opponent's ability to punch back that accumulates across the kind of long game a grindy aggro deck is already built to win.
