Ward (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays .) : Armored Armadillo gets +X/+0 until end of turn, where X is its toughness.

The value of X is determined as Armored Armadillo's activated ability resolves. It won't change later in the turn if other effects modify Armored Armadillo's toughness.
