Spirit en-Dal

Shadow is one of the most isolating evasion mechanics ever printed: a shadow creature lives in its own combat dimension, swinging freely past anything without shadow and unable to interact with the ground at all. That insularity is exactly what the Forecast ability here exploits. By revealing this card from hand during your upkeep, you can grant shadow to any creature for the turn, which does two things at once: it drops one of your beaters into the unblockable shadow plane, and it can pull an opposing blocker off the ground entirely, neutralizing it for a turn as a defender against your non-shadow attackers. The design tension is that the engine only works while the card stays in your hand. The most natural way to deploy a 2/1 (casting it) shuts the ability off, so you are choosing every upkeep between a body on the board and a recurring evasion grant you can fire once per turn. Forecast as a keyword was a brief experiment in upkeep-restricted, reveal-from-hand abilities, and this is among the cleaner illustrations of why the timing window matters: a sorcery-speed-ish, once-per-turn cost paid before combat, which lets you set up an alpha strike but never ambush a blocker after attackers are declared. It is a card that asks you to weaponize a mechanic by keeping it in reserve.
