How is this Mono Red Deck? MTG?

i would add "Shatter" to counter artifacts. "reverberate": for 2 red mana, copy target instant or sorcery spell. you may choose new targets for the copy. "Unstable Footing": 1red to play, damage can't be prevented this turn. 3 colorless and 1 red for the kicker: if unstable footing was kicked, it deals 5 damage to target player.
