Twinblade Paladin

Two payoffs feeding on the same resource. Every lifegain event does double duty here: it adds one +1/+1 counter to the body and it nudges you toward the 25-life mark that switches on double strike. The two clauses do not pull against each other; they stack, and the payoff is multiplicative, because once the toggle trips, each accumulated counter connects twice in a single combat. A 3/3 that has quietly grown to 7/7 on incidental triggers throws fourteen the moment you cross the threshold. Note the trigger's shape, though: it fires once per lifegain event, not per point, so a single big lifegain spell buys exactly one counter, while a Soul Warden ticking every upkeep or a table of lifelink attackers buys a counter every trigger. That is the deckbuilding lesson written into the card. Many small gains build the body far faster than one large one, so the reward is a shell that gains often rather than a shell that gains hard. The double-strike clause is a live-or-dead switch keyed to a life total, which makes it a genuinely different design from lifegain payoffs that scale smoothly: it wants you comfortably above 25, and it punishes a life total that yo-yos. The whole thing reads as a self-arming threat, where the same trickle that grows the creature is what flips it into overdrive and keeps it there.
