Sinew Sliver
The lord effect ported into white, and a quiet acknowledgment that Slivers were never going to stay a single-color tribe. Slivers began as a curiosity that shared keywords across the whole battlefield, friend and foe alike; the static +1/+1 anthem is the kind of pump most tribes get exactly once per color, dressed up in their own creature type. What makes this one structurally interesting is the symmetry the original Sliver design baked in: the buff applies to All Sliver creatures, not just yours, so in a mirror it feeds both sides. That open-ended wording is a liability the modern reprints quietly walked back, with later lords restricting the bonus to creatures you control. Mechanically it sits beside Muscle Sliver as a redundant copy of the same body-and-anthem package, which is precisely the point: tribal aggro wants its lords stacked four-and-four-and-four, and a second one-toughness lord that dies to the same removal is still worth running because the second copy doubles the effect of the first. The 1/1 frame is doing the honest work here. A lord that buffs itself is fragile by construction: the continuous bonus scales the whole team, but it also makes the enabler a bigger removal magnet, and the more lords resolve, the more catastrophic losing one becomes. Slivers historically asked you to win before that fragility caught up with you.
