Captivating Glance

Theft auras live and die on permanence, and this one hands the question of who keeps the creature back to the random number generator every turn. Most control-magic effects of this kind are binary: you pay the mana, you take the thing, and barring an enchantment-removal answer you own it for good. Here the steal renews at each of your end steps through a clash, and a clash is the gentlest coin-flip the game owns: reveal the top card, compare mana values, the higher wins. Lose the flip and the creature goes to the opponent you clashed with until you can win the comparison back. The design is doing something genuinely unusual for a theft spell, tying ongoing ownership to a recurring top-of-library lottery rather than to a one-time payment, which means the deck running it wants a high curve stacked toward the top of the library so the clash comes up favorable more often than not. That makes it a riskier proposition than its mana value suggests: not because the rate is bad, but because the effect is rented rather than bought, and the lease comes due every turn. The end-step timing matters too: the trigger resolves after your turn's work is done, so a creature you stole and swung with on your turn can walk back to your opponent before theirs begins if the clash betrays you. A theft that asks you to keep gambling for the creature every turn.
