Whirlpool Rider

A do-over engine stapled to a body, which is a stranger thing to build around than it looks. Most card draw replaces a known quantity with new cards; this one shuffles your entire hand back in and refills to that count, so the value is entirely a function of how many dead or spent cards you can dump. With three useless cards in hand, it cashes them for three fresh draws on the way to the battlefield; with a full hand of gas, it does nothing but spin the wheel. That asymmetry is the whole design tension: the effect scales with how badly your hand has stalled, which is the opposite of how most card advantage works. The same family of thinking produced Timetwister's symmetry and the later Day's Undoing line, but here it is scaled down to a single player's hand and welded to a 1/1 you can replay. The Merfolk type and the cheap cost hint at combo or loop ambitions: bounce it, replay it, refill again. What keeps the loop in check is that you are spending real cards each time and a fragile body to do it, so the cycle costs more than it returns unless something else is converting the shuffle into profit.
