The recent lumberjack changes are both a buff and a nerf and change how other cards interact with it, let's see the how the common decks will get affected

Lumberjack and Three Muskeeters

Lumberjack can no longer be played with three Muskeeters properly before double elixir without elixir collectors, you no longer can place him at the back and have elixir to play 3 musketeers in time

Lumberjack and double prince

It's better! Lumberjack doesn't get left behind by the charging princes.

Lumberjack and hog rider

Hog rider no longer outspeeds and goes past lumberjack which causes him to be accidentally targetted

Giant and lumberjack

They don't really go well together anymore... He's too fast and goes way ahead. He however can clear mobs faster and does more damage to clear mobs for the giant!

Lumberjack can also now do a ton of damage to a tower if left alone by himself
