Barrin, Tolarian Archmage

The bounce clause reads like the headline, but the second ability is the reason to run the body: this is a tempo swing wired to a card. Man-o'-War handed you a free bounce and walked away; this design converts that same enter-the-battlefield swing into card advantage, because the end-step trigger cares about any permanent that went from the battlefield to your hand this turn, not only what the Archmage itself returned. That widens the payoff considerably. Bounce a creature to dodge removal, return your own value permanent to replay it, or pick up something with an enter trigger you want to run back: any of it arms the draw, and because the end step arrives on the turn you deployed the Archmage, the card comes while you are still spending the tempo, no waiting for the body to survive a rotation. The self-bounce line is the sharpest, since returning a value creature and recasting it next turn keeps the engine ticking while you hold up interaction. The friction is elsewhere: a 2/2 for is fragile, and the draw is capped at one per turn no matter how much bounce you generate, so the reward is a steady drip of hand-returns rather than an explosive combo. It recasts the historical Tolarian wizard, once shorthand for raw card advantage, as a patient value engine that pays out on your own terms, permanent by permanent.
