Mox Tantalite
The classic Mox tension has always been that a free artifact accelerant is too good to exist without a leash: the original five paid in color restriction, and every printed-since successor has paid in something else. Here the price is time. The card carries an unpayable mana cost, so you never cast it from hand; you pay the suspend cost and exile it with three time counters, then wait. It ticks down across your upkeeps and only lands after the last counter comes off, at which point it finally resolves onto the battlefield ready to tap. Suspend it on turn one and it does not accelerate turn two: the counters clear on your fourth upkeep, so turn four is the earliest it produces mana. A Mox is normally the card that lets you get ahead early; this one buys nothing until your slowest, least contested turns have already gone by. What you get for the wait is a source of any color with no strings once it arrives, a rate the original Moxen never offered. It reframes the archetype as a patience play rather than a burst one: the acceleration is real but deferred, and a deck has to survive the stretch where the card does nothing at all. Bolting suspend onto a mana rock is a genuinely odd marriage, and the friction of those three idle turns is the entire reason a colorless any-color source is allowed to cost nothing.
