Silent Hallcreeper

An unblockable two-drop that snowballs is old news; what this design is really about is the modal choose-one-you-haven't-chosen structure, which turns a fragile 1/1 into a three-turn escalation curve. The first hit is a decision, not a payoff: two counters to survive and keep connecting, a card to fuel the deck, or the clone mode to poach a threat. Each connection unlocks the next tier, so the ceiling only arrives if the body lives long enough to spend all three, and the 1/1 frame plus enchantment-creature type is what keeps that from being a foregone conclusion. The clone clause is the sharpest piece and also the trickiest: because copy effects overwrite base characteristics, becoming a copy of another creature you control replaces the "can't be blocked" text along with everything else, so the mode is a genuine trade. You are surrendering evasion to double up on your best body, converting a value engine into a second copy of a threat that now has to earn its way through the red zone on its own merits. It is a rate that pays incrementally rather than up front, rewarding a board you have already built and a game you are already winning, which is precisely why it reads as small and plays large. The design goal is scale without a static engine: sequence the payoffs behind repeated hits and let the opponent decide whether removing a 1/1 is worth a card before it starts drawing them.
