Famished Paladin

The 3/3 body for two mana is cheap precisely because the static ability leaves the creature inert: it never untaps on its own, so its default state is a tapped wall. What redeems that is the triggered ability, and the redemption is total. Every time you gain life, this untaps, which matters most when the lifegain comes from the Paladin itself. Pair it with a free, repeatable outlet that taps it to gain a single life (Resplendent Mentor and Sorcerer's Wand are the canonical partners, but any zero-cost tap-for-life effect works) and the loop closes: tap to gain a life, the trigger untaps it, tap again, forever. That is the unusual shape of the design. Most two-drops with a drawback ask you to eat the downside in exchange for stats; this one hands you a combo piece where the static "doesn't untap" line is not a cost but the ratchet that gives the lifegain trigger something to release. The two abilities are load-bearing in opposite directions: the static clause locks the creature down, the triggered clause frees it, and only a lifegain outlet standing between them turns the pair into an engine. Absent that outlet it is a 3/3 that swings once and then sits, a deliberately dull baseline that keeps the card from doing anything in a deck not built to abuse it. It is worth exactly as much as the loop you assemble around it.
