Cauldron Curse

Enchant player
When The Cauldron Curse enters the battlefield, choose Toil or Trouble.
• Toil -The first spell enchanted player casts
each turn costs twice as much to cast. (That
player pays double the amount of each type of mana
that would be spent to cast the spell)
• Trouble -If a source would deal damage to enchanted player, it deals double that much
damage instead.
