yeah, it's also to deal damage and i wanted to keep it a 30 card fast-kill deck, and like Innominate saied, the deck would be a kill by mirror or jade sheild. Yes, the fire mark is enough to play the fire bucklers and it wins AI3 in about 10 turns. No, like in a monofire, it doesn't need defense because it focuces on killing your opponent as fast as possible, and I'm preety sure that in a couple turns of encoutuuring Eagle's eye, Unstable gas and Firewall any growth creature or dragon would die.
