Ghost Army

Here's all my tips and tricks for this deck:

Countess
- Put her at the backlines for enemy miners
- Never put her at the frontlines alone

Royal Ghost
- Always put ghost with the Countess and the DPS which is Pekka or Swordsman
- Depending on the matchup, if he opponent has no stuns like Mega Knight, Swordsman 2 star ability, Etc. Don't upgrade ghost
- The first star upgrade isn't that useful unless the opponent splits their minis up (Which is rare)
- The second star upgrade is one of the strongest upgrade for the ghost and is best to get this when the situation is allowing a ghost
- The third star upgrade is only ever useful if you fully invest to upgrade the ghost (Which costs 8 or 12 elixir to max)

Pekka
- The Pekka is one of your only tanks other than the Skeleton Guard, however he also can hit like a truck if left alone
- Pekka's first star is usually paired up with the last star upgrade because of the guaranteed crit chance
- Pekka's second star is really only used when Pekka is needed as a tank for the team or if Pekka keeps getting obliterated

Swordsman
- The Main DPS with it's insane potential for a team wipe if it gets it's boast out
- First star is a must have if you go all in on the swordsman because it grants its super back after a kill
- Second star is basically a must have because it's one of your only ways to prevent monk's super

Valkyrie
- Your side tank, it really depends on whether you needed another tank or need another DPS
- Only upgrade two times with the first and second star

Miner
- Miner is similar to the skeleton guard in which it is not needed to place but if you have spare elixir you may
- Miner is only needed for the dissipate to counter monks or other units
- Cleave might be a good idea if the enemy doesn't have many ranged units
