"The activation of your cards and effects that include an effect that Fusion Summons a Fusion Monster cannot be negated" would seem to impact things a bit.

Sure, Branded Lost doesn't stop you from chaining activation negation. You just won't negate the activation, which means you won't banish the card whose effect is activated. You'd still pay the cost and banish a "Myutant" card though.
