EvolveEvolve is a triggered ability. “Evolve” means “Whenever a creature you control enters, if that creature’s power is greater than this creature’s power and/or that creature’s toughness is greater than this creature’s toughness, put a +1/+1 counter on this creature.”
A creature “evolves” when one or more +1/+1 counters are put on it as a result of its evolve ability resolving.
A creature can’t have a greater power or toughness than a noncreature permanent.
If a creature has multiple instances of evolve, each triggers separately. (CR 702.100) (Whenever a creature you control enters, if that creature has greater power or toughness than this creature, put a +1/+1
counterTo counter a spell or ability is to cancel it: remove it from the stack without resolving it. A counter on an object or player is instead a marker that changes characteristics or interacts with rules or abilities; for example, a +1/+1 counter modifies a creature’s power and toughness. (CR 701.6; 122.1) on this creature.)

RegenerateIf the effect of a resolving spell or ability regenerates a permanent, it creates a replacement effect that protects the permanent the next time it would be destroyed this turn. In this case, “Regenerate [permanent]” means “The next time [permanent] would be destroyed this turn, instead remove all damage marked on it and its controller taps it. If it’s an attacking or blocking creature, remove it from combat.”
If the effect of a static ability regenerates a permanent, it replaces destruction with an alternate effect each time that permanent would be destroyed. In this case, “Regenerate [permanent]” means “Instead remove all damage marked on [permanent] and its controller taps it. If it’s an attacking or blocking creature, remove it from combat.”
Neither activating an ability that creates a regeneration shield nor casting a spell that creates a regeneration shield is the same as regenerating a permanent. Effects that say that a permanent can’t be regenerated don’t preclude such abilities from being activated or such spells from being cast; rather, they cause regeneration shields to not be applied.

healTo heal damage already dealt to a permanent, remove that marked damage from that permanent. If an effect states that damage already dealt to a permanent “is healed,” that permanent’s controller removes all marked damage from that permanent. (CR 701.69) all damage on it.)
