Ondu Knotmaster // Throw a Line
The two halves of this card are wired together through a single word: modified. Throw a Line, cast at sorcery speed on your own turn, drops two +1/+1 counters onto one or two target creatures, and the stat boost is almost incidental. What matters is that those bodies are now marked. When the Kor Rogue comes down from exile later and one of those modified creatures dies, it swallows two counters and swells into a lifelinking threat that gets larger the more your board trades away. The adventure is a setup spell, not a combat trick: it cannot ambush an attacker or blow out a block, only seed the graveyard-adjacent fuel the engine will feed on once it arrives. The counters do two jobs across the two halves, sizing a creature up for combat on the front end and serving as the payout currency on the back. The Orzhov pairing fits the loop precisely, marrying white's counter-and-lifegain habits to black's willingness to spend small creatures as resources. What the card wants is a board of little modified creatures you are content to lose, converting the ordinary tax of trading down into the very mechanism that assembles something big. Losing the fodder is the plan rather than the setback, and the single card that arms that plan is the same card that eventually collects on it.
