- The game checks whether it is legal to cast a spell before costs are determined or mana abilities are activated while casting it. If you no longer control a Desert after that point, perhaps because you sacrificed all of your Deserts while activating mana abilities, this won't affect whether you can legally cast Colossal Rattlewurm.
