The card ideas allowed into the game are limited, the cards that get nerfed are even fewer. Allmost nothing is banned from War, and none of the overpowered cards are banned from Leagues. In harsh times like these, the cards put into the game need to be anti-metagame cards; if not, Elements is just going to decline.
Fire is overpowered, or "complete". Whatever term you prefer. It's not just me, most of the good players have no doubt about it. And I really haven't seen anyone that can make a great argument against me. A couple other cards are overpowered as well. My list ends up looking like this:
Phoenix/Immolation
Fire Bolt
Graboid
Nova
Deflagration
Here are why these cards are overpowered (I'll edit this post each time I finish one of these).
The Phoenix + Immolation + Photon combo is extremely deadly with novas or a fire mark. Phoenix is an amazing card and only a couple creatures can match its strength. Phoenix is better than every single dragon in the game, which is unfair for Fire. It has a combination of a decent Attack:Cost ratio with very high resilience.
Phoenix has damage and resilience equal to Colossal Dragon with only 70% the cost. Phoenix has better resilience than Stone Dragon and only 1 less damage, but 3 less quanta cost. Phoenix has better resilience than Golden Dragon and 58% the cost to easily pay for the 3 worse damage. While Phoenix's damage and resilience is worse than that of Phase Dragon, Phoenix only has 54% the cost, making it the better choice. Phoenix has resilience just as good as the Colossal Dragon; both creatures can survive 3 Lightnings/Rage potions, or 2 Fire Bolts off of 20 quanta. Phoenix can also be killed by the user more easily if it is Antimattered or Frozen and revive, fully restored, something that Colossal Dragon cannot do. Phoenix possibly even has better resilience than the Stone and Golden Dragons. While it takes something like Infection more time to kill the Stone and Golden Dragons, common CC like Lighting and Rage Potion are much more effective on Stone or Golden Dragon. Phoenix can survive 2 Lightnings or Rage Potions, but Stone Dragon can only survive 1 before it is killed.
Phoenix easily beats the 6 Dragons with 10|5 or 9|6 stats. It can match or even have a better Attack:Cost ratio and much higher resilience. The 10|5 Dragons can't even survive a Lightning or Rage Potion, which are both very common. Phoenix can survive two and still have enough health to revive. Phoenix can beat the Attack:Cost ratios of 9|6 Dragons and has better resilience as well. The Dragons with 6 HP will die to a Fire Bolt off of 10 quanta or two hits from common CC cards: Lightning, Rage Potion, Shockwave, and a Fire Bolt off of <10 quanta. Phoenix can revive after taking 1-2 hits from these cards.
The only dragon that beats Phoenix's Attack:Cost Ratio is Crimson Dragon, but 3 hp with no ability is too frail for a 10-cost creature. Too many cards kill the Crimson Dragon for it to even compare to Phoenix, which is a much reliable and resilient choice with almost as much speed.
Just one dragon remains: Emerald Dragon. It is the only dragon that can match Phoenix's Attack:Cost ratio with good resilience as well. But Emerald Dragon is in an Element with no PC, no strong CC, and no Immolation. Phoenix has better resilience and better support, allowing it to be more easily used in a good deck.
It is normal for some cards to be stronger than others, for example, Phoenix being stronger than the Dragons. But what makes Phoenix overpowered is that it makes a perfect partner with Immolation. In a deck with 6 Immolations, 6 Phoenixes, and 6 Photons, Phoenix can be played on turn 1 more often than not. Any other deck with only 12 quanta sources will struggle to play a Dragon by turn 2, and often not even have a Dragon in play by turn 3. Immolation also gives 1 quanta of the other 11 Elements, which allows low cost cards such as Vampire Stiletto and Fog Shield to be splashed into an Immophoenix deck. Immolation gives Fire speed that no other Element can compare to. When it is combined with Phoenix, it becomes the fastest known unupgraded deck (source) (
http://elementscommunity.org/forum/index.php/topic,17173.msg234266#msg234266) and also has resilience better than almost every other creature with its damage.
The Immolation Phoenix combo is in a tier of its own.
Firestall: Fire doesn't just have the best rush; it has the best stall due to three key cards: Fire Bolt, Rage Potion, and Fahrenheit. Since stalls cause games to last long, a stall deck will have a huge surplus of quanta late in the match. No other Element can match the damage per turn of a Fahrenheit without using something vulnerable to CC. Fire also has the best bolt. Since bolts are usually used for CC, damage is a top priority. Fire bolt does 50% more damage than the other two bolts, which is definitely more valuable than the secondary effects of Ice Bolt and Drain Life. Fire also has Rage Potion. The only damage based CC cards that can beat the speed of Rage Potion are Lightning and Shockwave, but Aether and Air don't have a Bolt or weapon that can become extremely powerful with a lot of quanta. In BL, I've seen Firestall more than any other stall, which is because the other stalls can't match Firestall.
Just look at its stats: 8 damage for 4 quanta and a one turn delay. Nothing in the game can match that. Graboid also has versatility. It can stay unburrowed or burrow (if it has already become a shrieker) if something like Maxwell's Demon or Owl's Eye comes in to play, threatening to kill it. Other attackers like GotP, Mummy, and Toadfish can't do this. Graboid is extremely powerful, and it's the main reason QP Grabbow dominated BL until Sanctuary and GotP came out. But Graboid is still an extremely strong card, and only one creature can match its strength (Phoenix).
Nova rainbows need fewer quanta producing cards than mono and duo decks. A Nova rainbow can work well with only 8-10 quanta producing cards, but monos and duos need 12-14. Nova rainbows can have a much more efficient Deck Size:Quanta card ratio and can have an advantage over a lot of decks that aren't hard counters. Grabbow was very common in BL 1/2011 and it's still a great deck, partly because Nova allows few quanta cards to be necessary. If you need evidence, I finished 2nd place in BL 1/2011 (with a better W/L ratio than 1st place) by using Nova based rainbows almost every single game.
Shields and Weapons are important in almost every deck. Most of them can be destroyed by Deflagration, and most Shields and Weapons have a cost higher than 2 quanta. A player that uses Deflagration can gain a quanta advantage over their opponent by destroying a weapon or shield with a much higher cost than Deflagration itself. Because it's very important to use Shields and Weapons, Deflagration is a useful choice in almost every deck that uses Fire, and sometimes Fire is even splashed into decks only because of Deflagration. It's useful in almost every deck and no other PC card can match its cost.
Cards like Skull Shield and Black Hole are
bad examples of cards that should be made as anti-metagame cards. Skull Shield works against Immophoenix, but not against Firestall, and not very well against Grabbow. Black Hole is a decent card against Grabbow, but almost worthless against Firestall.
We need cards that are effective against most of the cards in my list. If you come up with an answer to Phoenix and Fire Bolt, don't make it weak to Deflagration. If you have an answer to Nova and Deflagration, don't make it fail against Fire Bolt. And lastly, don't make it overpowered itself. For example, Phoenix was created to counter heavy CC decks, but it became overpowered itself and solved nothing. If you need any help or clarification, just send me a PM.
