Does anyone play Magic: The Gathering, and if yes i need some answers about my deck?

My Magic deck consists of green. It has 18 land, 13 creature, 13 instant and sorcerys, and 10 artifacts and equipment. When i look through my deck for some combos, the only one that i can really find is my ageless entity. hes a 4-4 and gains a +1-+1 for every life i gain. i have 4 nourishes which give me 6 life and whisper silk cloak which makes equipped creature unblockable and cannot be target of spells or abilities. I have only lost twice with it, that was because i only drew 2-4 mana. but all the other times i have won. Is this a good deck even though thats the only combo THAT I CAN SEE?
