Latch Seeker

The math is brutally honest: three mana, three damage a turn, no questions asked. Unblockable is the cleanest evasion the game offers, free of the conditions that hedge flying or fear or skulk, and a 3/1 body translates that directly into a clock the defending player cannot interact with through combat. That same body is the price. One toughness puts it inside the range of nearly every burn spell, every ping, every random point of damage, and a 3/1 dies to the kind of blockless attrition aura and equipment decks happily trade into. The card is a chassis, not a threat in itself: its job is to carry whatever you bolt onto it (a sword, a pump aura, an instant-speed boost) into the red zone unanswered, turning a fragile attacker into a recurring source of unblockable damage that scales with your investment rather than its own stats. The design tension is the trade every voltron deck knows: the more you commit to the carrier, the worse a single removal spell hurts, and one toughness keeps that removal cheap and plentiful. What makes the package coherent is the color: blue rarely gets a proactive, evasive beater this cheap, so the Spirit's role is to give an otherwise reactive color a way to actually end the game by attacking, provided you can keep one mana's worth of removal off it.
