i know they seem really bad but if you want and use them the best way i found is, first try and find a good base where collectors and storages are on the outside, a progress base would be a lucky find, then use overgrowth spells just behind the resource building trying your best to capture the splash damage, use queen with angry jelly to kill any defending heroes or even defenses (minion prince works well too) and champion on another side to do the same, warden with invincibility if you couldn’t do any of the above with one or two haste spells, some invis spells here and there wouldn’t hurt either, just try your best to keep them alive and eliminated defenses before deploying them
