Ancestral Hot Dog Minotaur

Flying is an evasion ability.

A creature with flying can’t be blocked except by creatures with flying and/or reach. A creature with flying can block a creature with or without flying. (See rule 509, “Declare Blockers Step,” and rule 702.17, “Reach.”)

Multiple instances of flying on the same creature are redundant.

Afflict is a triggered ability. “Afflict N” means “Whenever this creature becomes blocked, defending player loses N life.”

If a creature has multiple instances of afflict, each triggers separately.
