Vigilance Whenever Agrus Kos becomes the target of an ability that targets only it, you may pay 1R/W. If you do, copy that ability for each other creature you control that ability could target. Each copy targets a different one of those creatures. (R/W can be paid with either R or W.)

Whenever this creature becomes the target of a spell or ability for the first time each turn, put a +1/+1 counter on it. As long as this creature has three or more +1/+1 counters on it, it has flying.

Enchant creature you control When this Aura enters, exile target nonland permanent an opponent controls until this Aura leaves the battlefield. Enchanted creature has ward 2. (Whenever it becomes the target of a spell or ability an opponent controls, counter it unless that player pays 2.)

Whenever another creature you control enters, you gain 1 life. 4W, T: Exile another target creature you control, then return it to the battlefield under its owner's control.

3W: Put a +1/+1 counter on another target attacking creature you control. If that creature is a Cat, it gains first strike until end of turn. (It deals combat damage before creatures without first strike.)

Vigilance At the beginning of your end step, untap each other artifact creature you control. 3W, T: Create a 5/5 colorless Vehicle artifact token named Zeppelin with flying and crew 3. (It has "Tap any number of creatures you control with total power 3 or more: This token becomes an artifact creature until end of turn.")

This creature enters with five reprieve counters on it. Whenever another nontoken creature you control dies, if its mana value was 1 or greater, you may remove that many reprieve counters from this creature. If you do, return that card to the battlefield under its owner's control.

Whenever another nontoken creature you control enters, if it wasn't cast, create a token that's a copy of that creature, except it's a 0/1 white Illusion. 1W, Sacrifice five Illusions: Exile target nonland permanent.
