Zhang Fei, Fierce Warrior

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.

Horsemanship is an evasion ability.

A creature with horsemanship can’t be blocked by creatures without horsemanship. A creature with horsemanship can block a creature with or without horsemanship. (See rule 509, “Declare Blockers Step.”)

Multiple instances of horsemanship on the same creature are redundant.
