# Cards
Cards are the most important element giving players an edge in PvP.
### Card features
There three **types of cards** in BattleMancers:\
(1) Troops\
(2) Spells\
(3) Buildings
Each card also comes with a rarity. There are 4 **types of rarity**:\
(1) Common (grey) - starts as lvl 1\
(2) Rare (blue) - starts as lvl 3\
(3) Epic (purple) - starts as lvl 6\
(4) Legendary (orange) - starts as lvl 9
Lastly, every card will have an energy cost to play. This cost (blue lightning) is usually associated with the strength of the card.
All the cards are upgradable in levels but not in rarity. A common card will always stay common but it can be upgraded up to level 14 just like other cards. The energy cost does not change as the cards are levelling up.
### Deck strategy
Higher rarity cards does not necessarily beat lower rarity cards because each card has some counters. For example, a maximum level legendary card with melee attack may not be able to kill a low level common air troop because the legendary cannot attack air. Some units are good against fighting single targets while other are good in crowd control and area damage. Higher levels and higher rarity certainly brings some advantages but with poor strategy they do not mean much.
