Ancient Tomb

The clean expression of a single design idea: that a land can be a mana accelerator if you let it bill you for the privilege. The two damage carries the whole balance. It is not a tax you pay once and forget; it is a recurring cost that scales with how badly you want the explosive starts, so the card builds a self-limiting clock into its own ramp. Tapping it on turn one to drop a two-mana threat a turn early is about as clean as acceleration gets, and the life total it eats is what stops that from being free power. The colorless output is what finishes the trade: the two mana arrives unfiltered, so the card is only as good as the decks that want generic acceleration into artifacts, big colorless threats, or activated abilities that do not care about color. That pairing of unconditional speed with a real, repeated price has kept it relevant across decades without ever needing a buff or earning a nerf. Where Sol Ring asks nothing and gives everything, this asks you to pay in the resource you cannot easily get back: a trade that only makes sense where games move fast enough to spend life like mana.
