This ability triggers only once each turn. {W}: Level 2 When this Class becomes level 2, create a token that's a copy of target token you control. {3}{W}: Level 3 Creature tokens you control get +2/+2.

Ward {3} (Whenever this enchantment becomes the target of a spell or ability an opponent controls, counter it unless that player pays {3}.) When this enchantment enters, exile target nonland permanent an opponent controls until this enchantment leaves the battlefield.
