Mishra's Juggernaut

Juggernaut has always been a study in the deal you strike with an efficient attacker: real power for the mana, in exchange for a body that cannot sit back. The archetype's founding member was a colorless 5/3 for four that had to attack, a rate that taught generations of players to point it at empty boards and swallow the trades. This version keeps the compulsory-attack clause and the fragile 3 toughness, then trades a point of the mana up and points the deal in a new direction: it wants those trades to happen, because a creature forced to swing every turn is a creature that dies, and a creature that dies wants to come back. That is what Unearth pays for. The graveyard becomes a second life, and the mandatory attack that used to be a straight liability becomes a feature you are happy to repeat, since the price for reuse is only mana. Red is where this bargain makes sense: the color already wants to empty its hand and refuel from the yard, and the haste-plus-trample off the return means the second appearance closes the same gap the first one opened, at instant readiness. The compulsory attack is the tax; Unearth is the color-appropriate way of paying it twice.
