If I use Intercept on an opponent's Caius, does Caius still resolve its effect?✓
Caius is Summoned and its effect is activated; Intercept is chained.
Caius is Chain Link 1 and Intercept is Chain Link 2. Intercept resolves first and negates Caius's effects, so Caius's effect will not resolve successfully.
If Intercept is chained to Caius, does Caius still activate?!
Caius is Tribute Summoned and Intercept is chained.
Caius activates as CL1 and Intercept is CL2, so Caius is taken.
