Skyfisher Spider

What earns the reach here is not the spider chassis: it's that the enter-the-battlefield trigger asks you to trade one of your own creatures for any nonland permanent on the board. The sacrifice is a conditional cost baked into a triggered "when you do" clause, which means the destruction only fires if you feed it something, and the removal is as flexible as removal gets: enchantment, artifact, planeswalker, creature, all fair game. That structure is why this reads as a value-engine payoff rather than a beater. It wants a board of expendable bodies to convert, and it pays you back on the way out: the death trigger gains you life proportional to how full your graveyard has grown, then exiles itself to keep the yard honest and shut off the recursion loops that a self-exile clause is specifically there to prevent. The design tension is the pull between the two triggers. The enter effect wants you dumping creatures into the yard early; the death effect rewards you for having done exactly that. So the card is really a payoff for a Golgari attrition plan that was already running before it showed up: token generators, sacrifice fodder, whatever keeps the graveyard filling. On an empty board it is a 3/3 that catches fliers and nothing more, and that gap between floor and ceiling is the whole point. It is a graveyard-count card wearing a removal spell's body.
