Eidolon of Philosophy
The math is calibrated to fail on purpose: to sacrifice a body you already spent a blue on, drawing three cards for an eight-mana total split across two turns' worth of commitment. That rate exists to disqualify the card from any deck trying to win before the game grinds to a halt. Its value lives entirely in the interim, where a 1/2 for one blue chumps early attackers, blocks a one-toughness aggressor for good, and becomes a resource once the board stalls. This is floor-filler by design: a body first, a lategame release valve second, priced so it never asks to be built around. The enchantment type is the one wrinkle that grants a second life, feeding constellation and enchantment-count synergies that care about a permanent's category rather than its stats. Absent those hooks, it is a patient, unremarkable blocker holding a card-draw option it will rarely reach a game slow enough to use.
