Deathtouch on a 2/3 is a lesson in how the keyword rewrites combat math without ever swinging. A creature that trades up against anything it blocks, and threatens a trade against anything that blocks it, freezes the board: opponents grow reluctant to send their fatties into a profitless exchange, and they hesitate to chump-block with their best creatures. Three toughness is the part of the line that earns its keep. It shrugs off the common pings and small burn of the early game, so the creature lives long enough for the deathtouch to mean something rather than dying before it ever threatens the trade. The 2/3 split is the quiet part of the design: a 1/4 cannot pressure at all, while a 3/2 would merely trade with a 2/2 instead of eating it and surviving, the extra toughness being exactly what lets this body win a fight clean. As a piece of black creature work, it does the structural job of a Royal Assassin without the activated ability: it does not pick off creatures on command, but it taxes every attack and block the opponent considers for as long as it sticks around. That is what the four mana buys. Not a removal spell, but a wall the opponent cannot profitably attack into, and a clock they cannot profitably block.
