So i am making a sand team with a core consisting of tyranitar and excadrill and i have, but i dont know where to go from there.

Something that tank ground and fighting moves, etc mantine.

A special attacker, prob should be able to break steel type such as skarmory, etc nidoking,electevire,togekiss

A piroity attacker to grab back momentom, etc bisharp (also gains on defog)

A secund counter to conk if enemy rocks put to much presure on mantine, etc impish arcanine? (idk conk can bring many diff sets)

Consider something that can stand agianst rain team, etc asault vest goodra.

Consider something against stall team, etc conk,azumarill

Consider something against sticky web, any kind of defog/spinner.
