Martinez signed Arouna Kone from former club Wigan to join Nikica Jelavic, Victor Anichebe and 21-year-old Apostolos Vellios, and the Spaniard expects all of them to play a big part this season.
Martinez said: "That's the type of decision you always want. When you've got three or four options to play up front, that's a great position to be in as a manager.
"I've been really happy with how different the strikers are. Apostolos Vellios has been working really well but then you've got three senior figures with Nikica Jelavic, Victor Anichebe and Arouna Kone. All three are going to be important.
"Probably the focus is not who's going to start on Saturday, it's more how strong the competition can be throughout the campaign because it's important to have effective strikers. They're all ready."
Martinez favoured a single striker for much of his time at Wigan, and former Everton boss David Moyes adopted the same policy at Goodison Park.
Versatility is the key word for Martinez, though, ahead of his first competitive match against Norwich at Carrow Road on Saturday.
"We need to be flexible," said Martinez.
"It's something we've been working on this pre-season to play in different systems, having different partnerships, and that's something we're going to carry on testing over the next few weeks."
Martinez has spent a lot of his first summer at Goodison Park fending off questions about the futures of Leighton Baines and Marouane Fellaini, who have both been strongly linked with moves to Manchester United to rejoin old boss Moyes.
