As I sit around the 300+ mark on a consistent basis; I have been able to see the top/middle/low end of the EFC spectrum. The difference in what it takes to win is slight...so slight in fact, that most matches are won or lost due to card choice. Not the draw, Not how you pilled, Not how your opponent pilled, but the difference in the choice of cards you chose to run at all. This subject is and can be very long winded, but I am going to simplify it. When choosing a card you need to be able to answer 1 very important question: Is this card strong or is this card competitive?
The answer you are looking for is....BOTH....but if you had to choose one...COMPETITIVE. A competitive card is specifically effective at a task and generally useful at a variety of jobs. I will give you 1 examples using data that is widely known.
Qubik was the number 1 card last week. This is due to it being both Strong/Competitve. It's raw Strength lies in it's average base stat total of 12 (7/5) for a 4 star card. It's competitiveness lies in it's multi-leveled use via it's ability and bonus. With it's bonus in play, Qubik is effectively a (8/5) card for 7 pills straight. With it's ability in play it can disrupt the opponents strategies at key points and guarantee it's 5 (7 fury) damage to always be true. It can be played on both offense and defense. It's more than just a SOA to throw at your opponents nasty abilities. It's a round winner. A true COMPETITOR. How many of your cards can say the same?
If you were to examine the top 10 for last week. You will find some similarities in the cards that should probably be introduced into your own card choice. The #1 similarity between all top 10 cards were that they had base stat totals averaging around 12. All of the four stars were at that total. The three stars were around 11. And the 1 5 star Christie was at 14. This means that 12 as an average should be the average total of as many cards as possible in your deck. The base stat is the most important stat. Some cards are strong via their abilities and gain power due to them, however when confronted with an SOA or SOB or the like...they lose what makes them special because they were always weak to begin with. This is the difference in Strength and Competitiveness. If you are looking for CONSISTENT results...you need to choose cards that give you consistent value...not situational value. If a card you would use can not win a fight reasonably without it's ability or bonus in play then you need to steer clear of those cards. 1 or 2 at most because the value they provide can be great when it works...but you need to be able to rely on the power your cards bring to the table every round. Then you can start to look at the abilities that they offer and the situations they provide to determine how COMPETITIVE the card is.
Gon's guide to the perfect EFC deck:
Step 1: Choose a main clan, things like La Junta, Fang Pi Clang, Freaks and Jungo. Pick 4 big cards.
Step 2: Choose a support clan, things like Pussycats and Roots, Junkz work too. Pick 4 control cards (SoB, SoA, Dr, Cancels and high base power).
Step 3: Go fight!
Step 4: Lose 7 fights in a row.
Step 5: Rescue.
