Krile (XIV) [Journey of Discovery]

When Krile (XIV) enters the field, if there are 3 or more different Elements among Characters you control, look at the top 4 cards of your deck. Add 1 card among them to your hand and return the other cards to the bottom of your deck in any order.
3: If the cost to use this ability was paid with CP of 3 or more different Elements, play 1 Character of cost 5 or less from your hand onto the field. You can only use this ability during your Main Phase.
