Chancellor of the Dross

The cycle of Chancellors all ask the same question: what is a card worth if you commit to it sight-unseen before the game starts? Here the answer is six points of life swung across the table on the very first upkeep, paid for by flashing the card from your opening hand and accepting that it then sits idle there until you find the seven mana to cast it. That tension is the whole design: the reveal rewards the most aggressive possible opening, while the seven-mana body it is stapled to wants nothing to do with aggression. You are not building toward a 6/6 with flying and lifelink; you are buying a turn-zero drain that happens to come attached to a creature you will probably never deploy. The reveal hits each opponent for three, then refunds that life back to you, which makes it a clean reach-and-stabilization piece for decks that win by attrition or by a fast clock, where three off the top is the difference between a turn and a turn-and-a-half of pressure. The Phyrexian framing fits the function: a bleed from hand with no spell on the stack to counter, no permanent to remove, just a number that ticks down before either player has drawn a card.
