Gramps is working well for this gate, though that's mostly because of NP3 I would guess. Though, I am able to Crit Medusa down without his NP if Jack Quick chains her NP on wave 2 and Gramps can Buster chain on wave 3. :|
Tonight's gate should be a different story though. I don't think a NP1 Quetz can 1-turn Nitocris unless I can Buster chain with the NP, and even than I still have doubts. Have Kintoki Rider of course, but he's Quick focused. Good backup though if it quickly becomes apparent that my Quetz will fall behind by a lot.
