Solstice Zealot

The energy on this body is a battery with exactly two charges, and the design ties them to a repeatable but rationed tapper. Each activation of the tap ability spends one energy, so the creature comes with two guaranteed uses of the effect and nothing more unless an outside source refills the counter. That framing matters: a free tapper would be an oppressive lock piece, but capping it at two charges out of the box turns it into a tempo tool that buys two combat steps or clears two blockers and then goes quiet. The tap targets any creature, not just attackers, so it doubles as a way to hold back a would-be blocker on your own turn or neutralize a mana creature during someone else's. Because the energy is banked rather than generated over time, this rewards decks that treat as a shared pool: pair it with other energy producers and the two-use cap becomes a starting balance rather than a ceiling. Absent that support, the 2/3 stalls a board twice and reverts to a plain blocker with a dormant ability; feed it, and the tapper stays online as long as the energy holds out. The whole design leans on that distinction between a self-contained interaction and a piece of a larger energy economy, and it lands squarely as the latter.
