Honor Guard

Every point of toughness here costs a full white mana, and that exchange rate is the whole design. The pump only ever touches toughness, never power, so no amount of mana invested turns a flooded hand into pressure: the 1/1 still swings for one whether you spend zero white or five. What it buys instead is durability on demand. It can shrug off a burn spell sized to kill it, refuse a combat trade the opponent expected to win, or plant itself in front of a larger attacker and survive. The repeatable button makes the creature a deterrent rather than a threat, a wall that forces a recount of the block math instead of a beater that scales. That defensive orientation places it among the earlier, more cautious takes on white's "cheap body with an attrition sink" idea, a template the color has revisited many times since. The instinct in later designs leans the other way: when a one-drop gets a repeatable mana outlet now, it usually grows the threat rather than just shoring up the floor. This one only ever raises the floor, and it does so one white mana at a time.
