Moment of Silence

Fog tends to come in green: it blanks one combat for one mana, every creature in the way fizzling for a turn. This is the white-flavored variant, and the difference in wording is the whole point. Where a Fog effect negates damage during the current combat regardless of whose creatures are involved, this targets a player and deletes their next combat phase before it arrives. The phase-skip framing is the design tell. Rather than fizzling damage, it removes the window in which that player's combat would occur, so there is no attack declaration, no attack triggers, no first-strike step, no combat damage from them: the structure of their fight simply does not happen. Note the constraint that prices that precision, though. The skip lasts only "this turn," which means it does real work only when cast on the turn of the player you want to stop, since a player attacks during their own turn. Note also what the wording does not touch: skipping a combat phase stops a player from attacking, but it does nothing to their ability to declare blockers when someone else attacks on a later turn. That makes this a defensive and political tool aimed at one attacker, not a board-wide shield like the green blanket. White rarely gets clean combat denial at this rate, and the single-target clause, with its narrow timing, is exactly what pays for it.
