Endless Sands

A blink effect smuggled inside a colorless mana source, which is most of what makes it strange. The land taps for one colorless mana like any other Desert, but its real work is the two-mana ability that exiles a creature you control, banked indefinitely until the sacrifice clause returns the whole stash at once. That structure separates the protection from the payoff: squirrel one threat away ahead of a board wipe, keep banking others over several turns, then cash them all in for a single repopulating swing. The friction is that nothing returns piecemeal; the only way to recover an exiled creature is to spend four mana and give up the land itself, so every blink commits you to eventually dismantling your own mana base. That cost is what keeps it from being a clean, repeatable flicker engine: it is a one-shot vault, not a turnstile. The design also sidesteps the usual blink template that returns creatures "at the beginning of the next end step" or under temporary control; here the exiled creatures simply stay gone until you choose to detonate, which makes the land both a long-term safety-deposit box and a delayed reanimation finisher. Wedged between a colorless source and a value engine, it asks you to treat your own creatures as a resource you can put on layaway.
