Archer Queen anti Wave Master

1st round
Place Magic Archer in the left corner and archer queen 1 tile diagonally
If you do not get a Magic Archer just put the archer queen in the same place

2nd round
Upgrade Magic Archer to upgrades 1 and 3
(If lost 1st round)
Place Giant Skeleton in front of the enemy tank

3rd round
Upgrade magic archer to 3 stars
Place Ice Wizard in front of Magic Archer
(If lost 2nd round)
Upgrade Giant skeleton to upgrade 2
Or if necessary upgrade Ice Wizard to upgrade 3

4th round
If you need to kill a long range unit place Bowler on it and upgrade to 2 if not place the Mega Knight beside the Giant Skeleton and upgrade Ice Wizard to upgrade 1
(If lost 3rd round)
Well good luck next game

5th round
Choose the most useful upgrade
Mega Knight upgrade 2 or 3
Bowler upgrade 1
Giant Skeleton upgrade 1

You can also replace the Mega Knight with PEKKA if you want

(If playing against wave master)
Just do the same strategy but instead of using the Giant Skeleton place the Bowler in the row of the Bandit/Wave Master

If you are curious for each mini here is a simple breakdown:

Archer Queen/Magic Archer: They are the main dps and they must stay together so the Archer Queen ability affects both

Ice Wizard: He helps by slowing down the enemies tank and also with his 3rd ability he stops all dart goblins and bowlers

Bowler: He is mainly for Wave Master counter but it also helps kill the long range units

Giant Skeleton/Mega Knight: They stop all enemies tanks by stunning them and helping the dps

Thanks for reading hope this helps out!
