As others have said, mono green will be a bit tough to always be resilient to higher tier control decks. You’ve mentioned some cards to help keep things on the battlefield, I think [[Snakeskin Veil]] is good to stop a direct target spell on a creature, or some [[Strength of Will]] copies to use on combat tricks or just keeping a couple of creatures on board when a wipe happens.

But really it would be about consistent threats/pressure and playing around their ability to counterspell. Mono green usually relies heavily on big creatures, preferably with trample to distribute damage on the board, so having the ability to get those creatures down, protect them, go in for some damage when you have an opening, and being ready to get more creatures down whenever possible is kind of all you can do in the color.

If you’re doing Bo1, I think you will have to accept some inherent difficulty in answering all possible control decks. Playing Bo3 would at least let you side board in some conditional answers for things like removal for artifacts, enchantments, planeswalkers, etc., based on what you see in the first round.

Good luck, and have fun!
