Nymris, Oona's Trickster

The reward condition is the design's whole tension: a 1/6 flyer with flash that only pays out when it acts on your opponents' turns, not your own. Casting on an enemy turn is exactly what a control deck wants to be doing anyway (instants, flash threats, reactive answers), so the card doesn't ask you to change your plan; it rewards the plan you already have. The filtering is a controlled version of impulse draw: look at two, keep one, bin the other, which turns the graveyard into fuel rather than a cost if you're playing anything that wants cards there. What keeps it from running away is the cap on your first spell each opponent turn, so it favors spreading interaction across the table rather than dumping a hand on one player's turn. The body is built to survive doing this: six toughness blocks nearly everything the ground throws at it and turns the flash-in into an ambush blocker as often as a threat. This is a blue-black tempo piece in the tradition of cards that convert held-up mana into card advantage, but it's tuned for a many-opponent table where "each opponent's turn" is three separate windows instead of one. Nymris is a value engine that only turns over when you play reactively, which is less a restriction than a statement about what deck it belongs in.
