Forum:Naturia/Plant Deck Needs Help!

Hello everybody. I have (Below) my Naturia/Plant Deck which needs to be perfected. Recently, I have been Dueling my friend who has an "Elemental Hero Prisma"/Gladiator Beast Deck and it is unbeatable! He Special Summons "Gladiator Beast Gyzarus" every Turn and there's nothing I can do about it because he starts his Turn by activating "Trap Stun". He also has an unbeatable Blackwing Deck, but moving on...

I have tried the "Super Solar Nutrient", "Lonefire Blossom" and "Gigaplant" Combo, but it is not enough. Please share your comments and feedback about this Deck.

Am I losing simply because this Deck is Tier 3? Thankyou. 002517.

Here is the Decklist:
