And that's why I love being able to set my own Field.

I took it down before it was able to set up with Amnesia. Silvally's Explosion deals massive damage even after the Defense buff. I still find that Garchomp more terrifying.

This time when I had Sawsbuck was my first time ever when I actually had a Grass-type against Terra. I don't generally like Grass.

I see... That's terrifying indeed.

However, imagine if you used the same seed (synthetic I reckon) on a 'mon of yours and proceeded to Skill Swap its Unaware! I already imagine myself doing it with a Giga Drain Venomoth. Quiver Dance up and destroy all of the remaining mons.

Or, just Gastro Acid it. Another quick idea. I prefer stealing its weapon and using it against it though  

Edit: Also, by removing its type, it also loses STAB. So, it won't be able to hit as hard, giving you the chance to set up!
