Kylorenne

Background

“Nothing will stand in my way… I must end what has been started!”

Advantages:

His Ability means that he will have anywhere from 6 to 12 Damage, without Fury, potentially KOing the opponent without any setup required.
His Bonus helps make up for his 6 Power to win the round.
If he is against a fellow 5* star card (who doesn't cancel or reduce any of his stats), he will be a 6/12 with -15 Opp Attack Min 5. A KOer that doesn't require much else than a 5* enemy (or a 4* + Fury) means he can be played more or less any round in the game.
This card's Ability works in the same direction as his Bonus. In T2 game modes( Hive is perfect for T2, and so is Kylorenne), this card is a scary opponent since it's almost a guaranteed KO possibility.

Disadvantages:

As a 5*, 6/2 base stats are abysmal.
He is no match for SoA, SoB, All Stops, Damage Reducers, or cards like Pandora. Since his Power is so low at 5*, he needs the Bonus to stand a chance against many other cards in the game. If his Damage-enhancing Ability is reduced or even stopped, he is a waste of Pillz with a measly 2 Damage.
Both his Ability and Bonus work best against a fellow 5*, who will surely have better coverage and then instantly have an advantage.
Overall, this card is a glass canon: The idea of a 1HKO is scary to be up against but he can be shut down by such a large variety of cards that he remains simply a good card and not a great one.
Since you want to make sure that he is against a 4* or 5* card, he can almost always only be played in Reprisal rounds (unless only against 4 and 5 star cards).
As a 5*, he takes up a lot of space in your deck (but in a T2 game mode that shouldn't matter anyway)
He has competition from other 5* in Hive (again, this shouldn't matter in a T2 deck).

He is based off of Kylo Ren, the main antagonist from Star Wars: The Force Awakens. His bio is based off of the quote he speaks in the movie when referring to Darth Vader.
In one of the few cards with a background that is very short.
The reason why he looks like a reindeer is related to the fact that he was released a day before Christmas eve and the "renne" part of his name is the French word for reindeer.
