Medusa, Inhuman Queen

Reach is a static ability.

A creature with flying can’t be blocked except by creatures with flying and/or reach. (See rule 509, “Declare Blockers Step,” and rule 702.9, “Flying.”)

Multiple instances of reach on the same creature are redundant.

Vigilance is a static ability that modifies the rules for the declare attackers step.

Attacking doesn’t cause creatures with vigilance to tap. (See rule 508, “Declare Attackers Step.”)

Multiple instances of vigilance on the same creature are redundant.
