Ive played sylvans literally non stop since they are my favourite deck. I havent used merchant raging build in a while(dont have 🔥 plants on new account) but the list looks decent. I personally play 3 shroom 3 leaf 3 guardioak 1 hermitree 2 rose lover 1 flowerknight 1 peaskeeper 2 carrot 3 carrot and 2 backrow atm- flowerknight peaskeeper are toolboxes if you mill both without hermitree its op.
I also have 1 lotuswain to recycle but that was before banlist cos it was super good now we have 3 marshaleaf im testing whether lotuswain is worth cos its dead in hand just for excavate eff
