First things first, you're gonna wanna make either a cerberus or phoenix by summoning two monsters (Usually by special summoning) corobane, mothman and any monster (or go the risky but effective route route) by norm summoning connector and aqua dolphin, you may want to also try and do the usual combo and end up with Dingusiu, time thief redoer and/or rusty.
If you're against a mirror, you could try a different route since they'll expect the same combo.
