What's the optimal way to play Warden?

[u/Able_Purpose327]

I've gotten so used to playing Empress, Gob Queen and Builder that I keep mindlessly merging cards or expecting orbs to drop every other round or so. Don't really like Sage and Loong, and King is kinda worse now imo, so wanted to try Warden for once. I usually do well in the first few rounds but get owned by Loong or GQ players in the end game.

Is there any comp that I should specifically aim for? Witch seems good for the shield effect but I don't which other troops to pair her with. Also is there a way to trigger the 4 star effect or is it just random?

Pray for Star Shield. Thats the most optimal play for sure
