Creatura — Gigante
5 / 6
Quando il Colosso della Cava entra nel campo di battaglia, metti una creatura bersaglio nel grimorio del suo proprietario subito sotto le prime X carte di quel grimorio, dove X è il numero di Pianure che controlli.
Quarry Colossus's ability is mandatory. If you control the only creatures when that ability triggers, you must choose a creature you control (which could be Quarry Colossus itself) as the target.
If there are fewer than X cards in that player's library, put the creature on the bottom of that library.
The value of X is determined as the ability resolves. If you control no Plains at that time, put the creature on top of that library.
