Lol na just really injoy the game tried alot of strategys one that works best for me is hitman and bear hunter combo of course with the ying yang rings its killer :)
Try to replace hitman with a shadow and try to get an Holgar early on instead of the Bearhunter ;) and see the possible change on your defense
Well the whole point is like this:
You start with Deckmaster (if you got it) and get holgar.
Build it as soon as possible. Trade in meads (do not drink them, if you kill the waves with only items) and trade them for Water of Life so you get an incredible drop bonus early on.
Carry with Holgar as long as possible. Mead production is running.
If you got Holgar as a stable carry tower, build a shadow somewhere so it can hit. Let him farm Stacks.
Given time, Shadow will start gettin more and more kills. The Stack ability is incredible strong.
The reason why this 2 towers are that good are simply:
They give you a benefit the whole game long and because of that they get stronger and stronger.
