Jailbreak Scheme

The base cost buys nothing here: both lines of text sit behind additional payments, so the floor is a single mode for one mana plus its rider and the ceiling is both modes for and together. That gating is the whole point. Where a plain modal spell hands you one printed effect for free, this forces mana to buy each line, and taking both is a real investment rather than an afterthought. The first mode grows a creature and lets it slip past blockers for the turn, a proactive attack trick when combat is what the board rewards. The second is the sharper tool: it sends an artifact or creature to the top or bottom of its owner's library, their choice. Handing the opponent that decision reads like a concession, but against a threat they want back it becomes a way to eat their draw step rather than simply returning the card to hand, the way ordinary bounce does. One card, then, that can act as a tempo answer or a combat enabler depending on what the turn asks for, with the mana cost of each mode doing the work a printed "choose one" clause normally does for free.
