Simple just draw and copy as much as you can, always try to copy Archmage Arugal and use Witchwood Piper to call him in case you don’t have it in your hand.Toki, Time-Tinker is just for fun. You also should copy your removal minions like Voodoo Doll . You also have Doomsayer –Frost Nova well know removal combo.
Try to make copies of all the minions with Archmage Arugal that he is the key to not run out of minions, also a good idea is to use Azalina Soulthief when you know you could get a good value from it.
