Fog

Damage-prevention spells that stop all combat damage that would be dealt during a turn, blanking an opposing alpha strike or buying a turn against an aggro board. Fog is the baseline one-mana version; Constant Mists adds buyback to recur every turn; Moment's Peace offers a second use via flashback; Arachnogenesis prevents the damage and also creates a wall of Spider tokens. Narrower than combat.combat_trick, which swings damage math by pumping power and toughness rather than nullifying it, and unrelated to combat.unblockable_granter evasion. Note these prevent damage only; they do not stop attack or combat-damage triggers from firing on declaration.
