Recurring Insight
Most "draw equal to a hand size" effects suffer a symmetry problem: you draw to parity with the opponent and end up no better off. This sidesteps it by drawing against their hand twice, on two separate turns, sampling whatever they happen to be holding each time. The front half resolves in your main phase against their current hand; rebound exiles the spell and lets you recast it free at your next upkeep, locked to that moment, after the opponent has had a full cycle to draw, untap, and either empty their hand or hoard answers. The decision is narrow rather than free: rebound triggers when it triggers, and your only choice is whether to take the second helping at that fixed window. So the calculus is about when to cast the front half, not when to collect the back. Most card draw scales off your own resources or a flat number; this one parasitically scales off the target, rewarding a read on the opponent's hand the way a duelist reads tempo. The price for that is that six mana buys nothing against an empty grip, so the spell wants a controlling shell that has already stabilized and now needs to bury the opponent under raw quantity. It is neither a tempo play nor a combo piece but a grind-out resource doubler whose ceiling is fixed entirely by how much the opponent is sitting on at two specific snapshots.
