Karsus Depthguard

Defender printed on a body that wants to attack: the tension is the whole design. A 4/3 for three mana is a fine aggressive rate, but the card ships stapled to the ground until you push its power to 5, at which point the defender restriction lifts and the wall becomes a swing. That conditional flips the usual logic of defensive creatures. Most walls with attack clauses key off some board state or a static payoff; this one keys off the one thing red loves to hand out anyway, which is raw power. A single +1/+0 gets it there, and past that threshold it stays an attacker for as long as the buff holds. The knife edge is that the enabling is fragile: shrink it back under 5 in response and it is a wall again, so the timing of when its power crosses the line matters as much as whether it does. The card wants a pump package that can hit the number on command rather than one that stumbles into it by accident, and it gives red a defensive early drop that never stops being a threat once that package comes online. The body is aggressive; the text tells it to wait.
