Monk 1-shot Easy Ladder

Your main strategies are to get monk to deal with everything, and to use the others logically.

The most important part is your positioning, since you win the first round you can wait for their other units or if you encounter the enemy deck often you roughly know where they are going to be so use that to your advantage.

1st round: Pekka and decoy adept at the front
Or if you are certain of what upgrade to take on monk take it now and place decoy.
(You should always win the first round)

2nd/3rd round: Get the 4 specialists buff over sea buff


Best upgrades to take:

Monk:
1st : take it if you are against priority melee hero/units such as SM, NB, PF or shark bait.
2nd : take it if they don't have burst or high DPS,
Extremely good against RC 4 royals,
3rd : almost never take it, only useful against backline if you have an angle (see counter for BK invulnerability)

Pekka:
1st -> 3rd
1st upgrade is really important for DPS, 3rd is still good but doesn't beat 1st upgrade, 2nd upgrade is basically useless in this deck (4specialists buff)

Swordsman:
1st -> 2nd -> 3rd
1st upgrade is also important for DPS, 2nd for sustain and 3rd for chaining kills. It is a good carry if enemy can counter Monk (especially with rogue buff).

Situational upgrades:

Fisherman:
3rd upgrade (kill faster frontline)

Decoy adept:
3rd upgrade (stun frontline)

Villager:
2nd upgrade (if they don't have really high DPS and villager can survive)

The other upgrades are bad with this deck.

Pump those trophies up and roll.
