Youll stay play some number of spellslinging creature payoffs like Guttersnipe or Storm-Kiln Artist, but its common for a spellslinger deck to run somewhere in the ballpark of only 10 creatures
That would be to draw lots of cards and find a way to win the game

Creatures with mana value of that quality can't block this turn
Have fun playing magic!
