Mirage Mirror

Most clone effects pick a lane: creatures, or artifacts, or a single permanent type. This one names four (artifact, creature, enchantment, land), and because the copy lasts only until end of turn before snapping back to a colorless rock, the card reads less like a threat and more like a repeatable answer that rents an effect rather than stealing it. Want a blocker on the opponent's turn? Hold up the two and copy the biggest thing across the table; the copy fades at the end of that turn, not yours, so nothing lingers to be exploited back. Facing a problematic enchantment or activated artifact? Become it and turn its own ability back on the board. The reach is the whole design: a single colorless permanent that can stand in for almost any threat type, folded into one three-mana artifact. The two-mana activation is genuine interaction, not just a proactive value play. You can leave the mana up and answer what resolves, the same posture a counterspell asks for, except the Mirror commits to a body or a static ability rather than a stack answer. The price is paid in mana every time, and the temporary duration means you are always re-buying the effect. It rewards reading the board over reading your own hand: the Mirror is only ever as good as the best permanent in play, and that permanent does not have to be yours.
