Lifeforce

An enchantment that asks for two green mana up front and then does nothing until you pour two more into it, and even then it only ever points at one of the five colors. The shape is revealing: a permanent that sits in play with no upkeep, gating its effect behind a repeated double-green payment. That structural choice tells you what the early design team thought a sideboard card should be. Not a single answer you cast once and discard, but a persistent tax that drained the opponent's tempo every time they tried to play their game. The double-green activation is the constraint that earns the rate: the card is cheap to leave on the table because actually using it costs real mana you would rather be spending on threats, so against a black deck you are still racing, just with a check the opponent has to plan around. Modern hosers have largely abandoned this template. Today's color hate tends to be a creature with a static ability, or a cheap split-card answer, because the design language now prizes cards that contribute even when the matchup does not show up. The activated-counterspell-enchantment belongs to an older philosophy, one where dedicating a sideboard slot meant dedicating it fully, and where a card that did nothing against four of the five colors was an acceptable cost for owning the fifth.
