Spectral Gateguards

Soulbond asks a creature to pay rent for the keyword it hands out, and this is the defensive end of that bargain: a wide, grindy 2/5 whose pairing gift is vigilance for both halves. A body built to sit back and trade on the ground is an odd carrier for an ability that rewards swinging, but that tension is the design. Vigilance on both creatures lets the pair attack and still hold the line a 2/5 was always going to hold, turning a stalled board into one that pressures without surrendering its blocks. The grant lives and dies with the wall: both creatures keep the keyword only as long as the Gateguards stay on the battlefield and the pairing holds, so the buff is anchored to the body least likely to die in combat, and a fresh creature can re-form the bond once the original partner is gone. Among the soulbond color slots, white lands at the cautious, board-stabilizing end of the mechanic rather than the explosive one: no extra power, no evasion, just permission to use a defensive creature offensively without giving anything up. The five toughness is what sells the role, surviving the smaller damage-based sweepers and staying chump-resistant enough to anchor a pair through several turns of attrition.
