Blockite

Summary
Blockite (or Elixir) is a main game mechanic that decides whether your troop gets to the field or not. If your Blockite hasn't reached the minimum cost of a card, it doesn't get deployed and: "Not Enough Elixir"

Match Mechanics
If you've played the game for a while, you'll know that you can't place troops until the game has started or in other words, reaching 10 Blockite. You'll also know that you can't place a troop if you don't reach the minimum cost of that troop, meaning you should wait which is a tricky move considering that you're not the only one that can deploy troops.

The main goal is to destroy your opponent's three towers using your troops and your Blockite. Using your Blockite efficiently can higher up these evens.

1x Elixir
1x Elixir means that your Blockite is steadily increasing in 1x Speed (about 0.5 - 1 seconds for 1 Blockite). This is the starting speed when you start a match. You can spam your cheap/ cycle troops, place buildings, or put a tank in the middle (troop magnet) in this phase for the later game as this phase takes two minutes. Players usually begin to prepare for the next phase or screw it and rush the towers, depending on who are you from those two.

2x Elixir
2x Elixir will begin after the 1x Elixir's 2 minute phase. Blockite will produce twice as fast as normal, making it the perfect time to cycle or spam cards. Medium-cost troops such as New-age Soldier are good at leveling the playing field. This phase lasts for one minute making it some sort of grace period for the next phase.

3x Elixir/Sudden death
When the equal amount of towers alive is the same for both you and your opponent for over 3 minutes, Sudden death will commence. Sudden death is where your Blockite Production is tripled (not doubled twice but tripled). Here, spamming tanks is now viable because of the amount of Blockite you get every second (3 per second). No matter how many towers are still alive, if one tower is fallen, whether your's or your opponent's, the match ends.

Strategy
There is quite a lot of strategy with Blockite, the way you use it is entirely dependent on your deck. There are two ways of using your Blockite:

Macro
Macro means looking at the big picture of the game (what cards your opponent has in cycle, how much elixir you have etc). Macro is primarily used in beatdown and control decks as they allow you defend the opponent's pushes while saving up for a big push.

Micro
Micro means card interactions (how much damage the card will do to the tower, will the card counter this card etc). Micro is primarily used in extremely cheap cycle decks as it forces your opponent to constantly defend, leaving them at low elixir constantly.

Tips for every deck
- Not Spamming

For people who spam troops, think twice, since spamming would often leave your Blockite supply to zero, which in turn allows your opponent (or A.I.) to attack and rush your tower. Its risky for intentionally going to zero Blockite as your opponent can place a tower-rusher like Engineer Noob since he/she/it knows that you have nothing to defend, leaving them with a free tower

- Counter-attacking expensive troops with cheap troops
Using cheap and effective cards against more expensive cards like tanks or swarms can give you the upper hand as it disadvantages your opponent by having more Blockite to use. (eg. Lightning Strike (4) v.s. Noob Horde (5): Lightning Strike wins with 1 extra Blockite)

- Having a building
Having buildings can turn the tides of battles by simply placing one, whatever the building. For such, Eternal Fountain can produce more Blockite; Noob Hut for extra troops/meat shields for the span of the battle; Sniper Tower for defense; etc.; and more, depending on what building you chose. Not only that, but when you place three buildings, that's one less card to cycle!
