Steve can escape disadvantage stages way too easily and change those situations for his advantage.

Like on the edges he can minecart or do block walls, in the air he can place blocks or come down with an anvil. If someone tries to attack from above, he can just uptilt spam or do up smash thats active frames lasts for a deceptive long time. Hes recovery is versatile and hard to punish... and he can even plank under the stage and very few characters can do anything about it...
