The drawback is the whole personality here, and it is brutal in a way that later "free" fatties rarely are. To cast a 12/12 trampler for seven, you pay twice: five lands to the graveyard the moment it lands, and then the body comes in tapped and refuses to untap on its own. That second cost is the cruel one. Having gutted your own mana base, you now need to keep replaying Islands just to swing, turning the Leviathan into a strange engine that punishes you for not drawing lands and rewards you for the exact thing the sacrifice clause stripped away. It belongs to a line of early blue sea monsters built around enormous bodies gated behind self-sabotage, where the design lesson was that raw size is cheap if the activation tax is steep enough. The land-sacrifice plus tapped-and-stays-tapped combination is one of the steepest taxes the era produced, and it poses a riddle: how do you flood the board with Islands after you have just thrown five lands away? Answer that and you have a trampling finisher attacking on a cadence you control through land drops rather than the untap step. Fail to answer it and you have a 12/12 statue staring at an empty mana base, which is precisely the tension the design dramatizes.
