Ruthless Ripper

Most morph creatures charge mana to flip; this one only asks you to reveal a black card already in your hand, which makes the unmorph functionally free and impossible to telegraph until the moment it lands. That changes how the card threatens. The face-down body is a 2/2 that reads as a fair blocker, but the deathtouch underneath turns any attack into it a trade the opponent almost never wants, and the flip trigger staples two life lost to the reveal: not damage, so it slips past any prevention or fog the opponent has banked, and not a drain, so you gain nothing back. The cost is paid in commitment, not mana: showing a black card rewards a deck already saturated in its color rather than handing the trick to a light splash, and it costs you nothing but the information of what you are holding. Cast openly on turn one, it does the early work of a cheap deathtouching one-drop, the kind of creature that makes opposing attackers think twice. Held back as a morph, it sits as a defensive 2/2 that punishes combat and waits for the turn you choose to spring it. The two modes cover different stretches of a game: a curve-filling interactive body at the front, a reach-bearing combat trap in the middle, and a burst of life loss whenever you decide the window has opened.
