It looks like Powers "won" the vote so I am ranking Powers now. I am ranking them based on how helpful they are when they are normally used, as every single power can't be used in every situation.
Let's get into it!
And the worst power is...
#9 Greed Power - F Tier: You don't need this Power. Like, at all. It is basically Steal, just you have a chance to get a slightly higher amount of coins. Still you really don't ever need to use this Power and use should be better off with any of the other Powers. Greed Power gets last place.
#8 Challenge Power - D Tier: You can't survive with this Power. Literally. The buffs this power gives are good, but the debuffs...oh no. -15% health, -1 damage, -1 defense. Your survivability goes down a lot. Why is this Power not last, let alone in F Tier? Well it has a use. To help grinding for cards and gear, but if you want to use this, then bring some friends. You will not be surviving long with this Power by yourself. The Challenge Power is way too risky and ends up being your downfall most of the time, so Challenge Power takes 8th place.
#7 XP Power - D Tier: This power gives you extra XP after battles, which is nice. When you get to MAX level though...it losses all purpose, and is the worst power in the game. Its good use before you hit MAX level is good enough at least to jump over two of the Powers. Still, it doing nothing when you hit MAX level isn't going to get you a top spot, so XP Power gets 7th place.
#6 Flower Power - C Tier: Flower Power makes items better. Or specifically ones that heal a lot. Healing extra HP from Hoagies and Cheeseburgers is such a mediocre use. How commonly used though, Hoagies and Cheeseburgers, give its use more purpose, thus being able to climb to 6th place.
#5 Snowman Power - B Tier: This power gives a chance for snowmen to appear on the battlefield. When you get enough cards, you eventually get the Summon Snowman skill, which is good for tanking hits. Snowman Power has a useful purpose. This gives it the 5th spot
#4 Regain Power - B Tier: At first glance, this use seems kind of mediocre. At closer inspection, it is better than you think. This can help you use stronger attacks after using Fury, that is after you used something to give you an SP boost. Getting one extra SP can be the determining factor of a match. I am not kidding when this thing has the potential of saving you in a tough situation. This Power is pretty helpful to have, giving Regain Power 4th place.
#3 Wraith Power - A Tier: The same as the Snowman Power, but with enough grinding gives you a more useful and powerful move. It is just better than Snowman Power, and nothing really else to it. This gives Wraith Power 3rd place.
#2 Bravery Power - S Tier: This power is pretty simple. Gives you an attack boost if your HP gets below 25%. This is a nice attack boost that even lasts multiple turns, meaning you can afford to take a turn to heal if you can. It is even better if a friend heals you so you can use your attack boost multiple times or if a friend powers you up so the turns of the boost last longer. This move has plenty of uses and definitely deserves 2nd place.
And the best Power is...
#1 Summoning Power - S Tier: This one is probably confusing, so let me defend myself. All summons greatly benefit from the +3 HP and +1 Attack. Abby and Tangler get much needed HP and their attacks are more helpful and damaging. Sadly, Snowmen don't inherit the Attack increase, but they do get the HP boost, meaning they can tank more hits, making the thing they do great even better. I hope everyone understands why I put Summoning Power at the top. Its amazing buffs to summons are hard to ignore, and makes summons much more useful and worthwhile, putting Summoning Power at 1st place.
I won't be ranking anything for a little bit, but I will come back and rank items and enemies. Maybe even come back with a new area idea who knows. Hope everyone has a great day! Good-bye.
