What happened to Mono Red decks ?

Red has lost a lot .... It has lost amazing burn spells: Lightning Bolt, Burst Lightning, Forked Bolt, Searing Blaze, and Staggershock. It’s lost terrific aggressive creatures: Goblin Guide, Plated Geopede, Kargan Dragonlord, and Kiln Fiend. Gone are the combo cards: Pyromancer Ascension and Splinter Twin. Red is no longer the power color in Standard.
