Dauthi Embrace

Black's answer to the question of how to make any creature on the board blockable by, or able to block, only creatures with shadow, for as long as you can pay for it. Tempest's evasion experiment locked the Dauthi and Soltari aggressors into their own combat dimension, walling them off from a ground board with no way to interpose; this enchantment rents that same dimensional escape to any creature, instant-speed, with no limit on how often you fire it. The design logic is repeatability bought one pump at a time rather than sold once: each grant is temporary and tied to a fresh payment, so the card never resolves into a permanent unblockable-maker the way a stapled-on keyword would. Timing is the whole game. Activate on your attacker before blockers are declared and the defender's legal blocking pool collapses to nothing on a board without its own evasive creatures, so the swing lands clean. Activate on an opposing blocker and you pull it out of the non-evasive combat math entirely, clearing the path for your ground attack. The double-black cost meters the engine: pushing one large threat through is cheap, but funneling a whole board drains your mana in a hurry, and demanding two open black sources rather than a single floating mana makes holding up the threat a genuine commitment of your turn. This is a payoff for already living in black's evasion subtheme, not a splashable trick.
