The strategy is build up your mana, then use big card, core of this deck is Guardian Animals, get it in your start hand or start with grow mana card, then use corrupted Strong man
Then buff with Suvival of Fittest and one shot your opponent, Sheldras is quite fun if your opponent is no aggro,
But i recommend Guardian of Animals, then Primodial protector, then Survival of fittest, then go to your opponent face.
If you have cards, just try this, I stuck from D5 in this month, just get Legend today, have fun 🙂
