Indeedee is able to lure in many of the Pokemon that might be switch-ins to Cofagrigus, which is a pretty short list. Clefairy gets easily 2HKOd by Psyshock or crippled with Trick, Alcremie is 2HKOd, and Dark-types such as Skuntank and Sivlally-Dark [despite them not really being checks to Cofag] can be lured in and 2HKOd by Dazzling Gleam. Quagsire and Rotom-Fan are two Cofag checks not lured in by Indeedee, but Indeedee can freely switch into them and use them as an opportunity to wallbreak. Pokemon that can come in on Indeedee with a correct prediction, such as Ferroseed, are set-up bait for Cofagrigus.
In return, some teams may have no way to severely damage Cofagrigus except for a Dark-type; Cofagrigus can severely damage or KO them with Body Press, making it pretty much free for Indeedee to spam its terrain-boosted Psychic-type attacks.
Finally, if you choose to give up one of the other moves, Indeedee-F can also run Healing Wish to restore Cofagrigus back to full health, curing its status and giving it another chance to sweep.
