Any power- or toughness-modifying effects (those that give +N/+N, for example) and counters will apply to the creature’s new base power and toughness, even if they started to apply before Illusory Wrappings became attached.

Illusory Wrappings overwrites all previous effects that set the creature’s base power and toughness to specific values, including those that define a * such as that of Enigma Drake. Any power- or toughness-setting effects that start to apply to a creature after Illusory Wrappings becomes attached to it will overwrite this effect.
