Please don't suggest cards such as Mirror Force, Pot of Duality, Solemn Warning, etc. because I don't have them yet. However, when I do get them, I'll put them in.

Right now, I'm using Junk Synchron as a substitute for Gale because I think it is the best level 3 Tuner next to Gale. It can get a Machina Peacekeeper from my Graveyard, and when I Synchro Summon Black Rose Dragon (Junk Synchron + Gadget) I can destroy all cards on the field and with Peacekeeper's effect, I can get a Gearframe from my deck. But when I get a Gale, I will definitely take Junk Synchron out and put Gale.
