Dawnglare Invoker

A 2/1 flier that chips in early and then quietly becomes a mana sink once the board stalls: that is the whole arc of this design. The activated ability's price is the gamble, a number high enough to read as unplayable until you account for what it buys. Tapping every creature a single player controls is not a Sleep-grade lock (their creatures untap on their own turn), so this never wins a race; it ends a stalemate that the race already failed to resolve. You point it at one player, leave your own attackers untapped, and punch through a single swing per turn while pouring excess lands into the sink. The targeting clause is what makes the tap one-sided rather than a symmetrical wrath of motion: it names a player, not the board, so it enables an alpha strike instead of freezing the field for everyone. This is the manlands-and-mana-sinks school of white at its cleanest, where a cheap evasive body is the early honest work and the activated ability is the real payoff, priced so steeply that flooding becomes a resource instead of dead draws. The body never costs you a turn while you assemble the cost, which is exactly why the steep price is affordable: you are not building around the ability, you are letting the game hand it to you when nothing else closes.
