Simple enough
Junk = *4&*5 synchro engine (mostly *5)
Pilica = *4-*6 synchro engine as long as u have corresponding level in the gy, with restrictions only wind monster u can summon in that turn
I feel like I've won more games destroying a backrow with Snipe Hunter than I've lost rolling a 1 or 6. Plus, you're still kinda gambling on having a high-level Machine in your hand anyway, which isn't a guarantee.
