Watcher for Tomorrow
Hideaway spent its early life shackled to a payoff: a land or an enchantment that only surrendered its buried card once some tall condition got met, which meant most of those cards were combo pieces or nothing. This design snips that leash. The exiled card is not locked behind a trigger you have to engineer; it comes back the moment the body leaves the battlefield, and that clause is far wider than a death trigger. A removal spell hands it over, sure, but so does a sacrifice to a later engine, or, most tellingly for a blue two-drop, a blink or a bounce. Flickering the creature is not wasted motion: it returns the exiled card to hand and reloads the dig, turning a value hit into a repeatable one. So the selection carries the weight. You look at four, keep the best, and cashing it in means moving a fragile 2/1 you were probably going to move anyway. The enters-tapped clause is part of the price: no ambush block the turn it lands, no immediate swing, so the card wants to be routed through your own blink and bounce effects rather than sent into combat. That reframes hideaway from a combo mechanic into a value one. The random-bottom clause on the other three cards is the restriction that stays: you choose one of four, not stack your deck, and the rest scatter beyond reach. A small card that resolved a real tension in an old keyword, and the fix was less about power than about choosing a trigger the deck naturally pulls.
