The last clause is the one that turns a licensed-character card into a design object worth studying. Most "grows on death" abilities count deaths flat: a counter per creature, a trigger per sacrifice. This one only fires when the creature that died was bigger than the drow, and it hands over exactly the size difference. The effect scales inversely to how well the plan is already going: while the board is small the counters trickle, but the moment something genuinely threatening dies (a fatty, an opposing commander, a token doubled into relevance) the payoff arrives in one lump proportional to the threat that just left. It rewards you for surviving the largest thing on the table rather than for grinding through chaff, which is a sharper decision than the usual death-counter engine offers. Double strike is what makes the accumulated counters lethal instead of merely large: every +1/+1 lands twice in combat, so a body that has fed on a few oversized deaths converts to damage far past its printed size. Guenhwyvar arrives as a legendary 4/1 with trample, a hard-hitting attacker whose fragile toughness is itself a candidate for the death trigger if it trades up. The whole package reads as flavor first, but the counters-from-difference clause is the mechanically novel part: a growth condition keyed not to the fact of death but to the magnitude of what was lost.
