Invasion of Shandalar // Leyline Surge
A Regrowth stapled to a Battle produces something genuinely strange: a card whose destruction is the goal, engineered by the player who owns it. The entry payoff is immediate, returning up to three permanent cards from your graveyard to hand, but the Siege's protect-and-attack rules turn its own defeat into the puzzle. You nominate an opponent to defend it while you and everyone else swing at it, and knocking it down exiles the Battle to recast it transformed as Leyline Surge. In multiplayer that creates a genuine tug-of-war: the defender wants the Siege standing precisely to withhold the back half, while you push through their defense to trigger the flip when it suits you. Since you usually command most of the attackers, you decide the timing rather than waiting on the table. Once flipped, Leyline Surge is an upkeep engine that lands a permanent from your hand each turn at no cost. What makes the two halves cohere, where most transforming cards ask for contradictory board states, is that both want the same fuel from different zones: the recursion side rewards a graveyard packed with fat permanents, the enchantment side rewards a hand reloaded with them. Refill from the yard, then dispense from the hand a permanent at a time. Two mouths feeding on the same diet of expensive permanents, one drawing them up from the dead and one dropping them into play.
