Taigam's Strike

The whole pitch here is doubling: rebound takes a four-mana evasion-and-pump effect and pays it out twice, once on cast and again at your next upkeep for free. That second resolution is what reframes the card. A single +2/+0 unblockable swing is a thin payoff for four mana at sorcery speed; the same effect spread across two consecutive turns is closer to a two-card commitment paid up front. The structure rewards a board that holds, but the flexibility lives in the recast: the second copy comes off exile as a fresh cast, so you choose a new target on your following upkeep. If the creature it pointed at dies between turns, the back half simply lands on a different attacker. That makes the unblockable clause the real engine, not the pump, on any threat with a connect trigger, lifelink, or a saboteur effect, where getting through unblocked matters more than the extra two power. What you give up is timing rather than targeting: rebound exiles the spell and dictates when the second cast happens, so you cannot bank it for a more decisive turn, and you cannot hold it up as an instant-speed combat surprise. The sorcery speed and the upkeep schedule tell you the design wants this used proactively, planning two attack steps ahead, with the payoff assuming you still have a worthwhile body to send through when the free cast comes due.
