I've come up with the invincible strategy for those of you who want to destroy 30win.
Don't know why I can't upload images.
This game is extremely fun and I've been absolutely ADDICTED to it every day for a whole week
Ive tried multiple fun strategies like chef, jester, farmer, recruit, but this one is the strongest
Now here's the strategy, but its too strong that makes the game suddenly kind of boring so WARNING:
Early Stage: aiming for as much drummer as possible, and eliminate as much as possible health loss. This is done through using warrior to form a berserker. You could also buy jester, and money bag for money store or free turns.
Middle stage: Merge to for a tambornist. Then buy as many paladins as possible and upgrade. Also can build one card thrower or card master. When you have nothing to buy, just buy money bag and then sell it(due to tambornist).
Ending: You should be unstoppable now. Only aim for shield and buy as much as possible. No need for gears.
The final lineup should look like this: Tambornist, Card Master, Blinded by light*3.
Reason how this works: Tambornist provides attack, shield means no need for health, thus no gear is needed.
Have fun! Awesome game! Hope to have a realtime 1v1 mode.
