First deck in years

{"ops":[{"insert":"Hi guys, I'm getting back into MTG after stopping years ago. Back when Urza's Saga was still out, I had a HUGE, very valuable collection stolen from me and I quit in frustration. I want to get back into it though and want your guys' advice on this deck. \n\nThe concept is pretty simple, I use green cards to pump up my cheap, fast red creatures, attack, the sacrifice them for more damage with cards like Thud. I have a couple small mana ramps in there because it's very common to be one or two mana away from a round 4 win. I think it may need just a bit more though, maybe swap some of the lands out for forests, and run orcish lumberjack? Idk just wanted to get some opinions because I'm feeling a bit overwhelmed, trying to put a deck together. \n\nhttps://archidekt.com/decks/15693238/secret_santa\n"}]}
