Who needs instants, sorceries, and enchantments when you have creatures? Lots of creatures that provide value you're more likely to see in some instants or sorceries.
The main thought behind this deck is to fill the board and take over.
Crimson Mage
can give any of my creatures haste when needed.
Heartwood Storyteller
helps keep my foot on the gas for each time my opponent plays a non-creature spell.
Deus of Calamity
can start making lands disappear if not stopped, making it a serious threat.
Kird Ape is big value for cheap.
Primal Forcemage
is like a free Giant Growth every time a creature hits the field. With
Crimson Mage
out to push haste out, even smaller creatures become a threat.
Ruric Thar, the Unbowed punishes anyone for even thinking that a spell comes close to the power of a creature.
Taurean Mauler gets bigger and bigger for every spell my opponent plays and becomes a big threat very quickly.
Ulvenwald Tracker can be used as removal as my creatures will probably be bigger than the opponents in many cases, helping to shift the board state in my favor.
Voyaging Satyr
helps with ramp and mana fixing. Especially useful when used on a Gruul Turf.
Ghor-Clan Rampager and Wasteland Viper can hit the battlefield on their own or simply bloodrush to push something already on the board.
