Rambling Possum

Most Mounts treat saddling as a sunk cost: you tap creatures to power up the attacker and eat the tempo hit, hoping the payoff outweighs the bodies you've committed to the crew. This one refunds the deposit. The bounce clause turns each saddling into a temporary loan rather than a spent turn, so the creatures that tapped to fuel the attack come home to your hand instead of sitting exhausted through your opponent's turn. That reframes the whole cost structure of the Saddle keyword. Because saddling only needs total power 1 to switch on, the natural fuel is enters-the-battlefield creatures and other cheap value engines, and returning them lets you replay the trigger next turn. The +1/+2 is almost incidental to that engine; it makes the possum a slightly harder swing, but the reason to build around it is the recursion loop, not the stat bump. The catch that keeps it grounded: saddling is sorcery-speed, so you can only assemble the crew on your own main phase, and the bounce happens after the attack, meaning you spend a turn's worth of board presence to recur it. It rewards a deck already full of creatures that want to leave and re-enter, and does very little in one built around static bodies that would rather stay put.
