Dross Crocodile

The 5/1 is the oldest punchline in the game, and few executions are cleaner: maximum power, no defense, no evasion, no upside. Black has carried this body forever, the willingness to trade a creature's survival entirely for raw offense. The math is brutal in both directions. Five damage is a fast clock, enough to put a real timer on a control opponent, but a single point of incidental damage, a chump, or any combat where it isn't the attacker erases it. It dies to its own ambition. What keeps a vanilla glass cannon like this from being a pure beginner's trap is that it makes no demands on the deck around it: no tribe to assemble, no counters to manage, no graveyard to build. This is the simplest possible aggressive proposition. Spend four mana, threaten five, and accept that you have committed a creature the worst removal in any format can answer with mana to spare. Designs like this exist to teach a lesson about rate that the rest of the card pool spends its time qualifying: power is the cheapest stat, and toughness is what you actually pay for.
