Multiform Wonder

A self-contained energy battery wearing the body of a 3/3, and that self-sufficiency is what sets it apart from its era's other energy cards. Most of them asked you to assemble a deck that generated the resource elsewhere; this construct walks in with three counters already in hand and a menu of ways to spend them. The first ability buys an evasion or defensive keyword for a turn; the second is the more interesting half, a stat-swap that pushes the body to 5/1 to punch through or 1/5 to wall an attacker, on demand. Because both modes activate at instant speed, the construct is never quite the creature your opponent blocks. It can become a 1/5 to absorb a swing it would otherwise lose to, then reconfigure into a 5/1 the following turn to threaten a kill, choosing its profile in response to whatever combat is in front of it. The constraint is arithmetic: three energy is all it brings, so the toolbox is finite unless something refuels it, and every keyword or stat-shift drains the same small pool. That tension between flexibility and exhaustion is the point. On its own it does a little of everything for a few turns and then settles into an ordinary 3/3; given an external energy source it becomes a genuinely slippery threat that rebuilds itself around the board state each turn.
