A deck a recently created that took me to masters last season.
Valley Spring fits surprisingly nicely into a typical midrange Dino deck, but instead I chose to lean more into it and added Twining Ritual and Rolling Spineback to keep low cost dinos in your hand at all times, as well as single copies of some choice dinos to play off Tableau
Removal depends almost entirely on Killer and Copy tactics, which works well when it gets rolling due to Clutchmate being a crazy card, but can be inconsistent. I decided to leave out a market in order to fit in more single copy bombs, but you can easily substitute merchants in.
