So basically I stopped playing for a while, but I've started back up and am continuing a Mono-Grass run I started. I'm pretty much stumped at how to beat Serra at this point. I can't even come close with my current team:
Ludicolo
Lv 46 / Swift Swim
Giga Drain
Rain Dance
Bubble Beam
Hydro Pump
Roselia
Lv 46 / Poison Point
Giga Drain
Synthesis
Grass Whistle
Toxic Spikes
Exegguter
Lv 46 / Chlorophyll
Leaf Storm
Extrasensory
Poison Powder
Sleep Powder
Tangrowth
Lv 46 / Regenerator
Ancient Power
Knock Off
Rock Smash
Giga Drain
Gourgeist
Lv 47 / Pickup
Leech Seed
Pain Split
Shadow Ball
Destiny Bond
Jumpluff
Lv 48 / Chlorophyll
Leech Seed
Sleep Powder
Mega Drain
Acrobatics
Torterra
Lv 50 / Shell Armor
Crunch
Synthesis
Earthquake
Razor Leaf
As you guys can probably see, my team has a bit of an issue with ice types (My only super effective move being Ancient Powder on Tangrowth, who gets one-hit KO'd by most of Serra's Pokemon).
I've been thinking of trying a dual-type Grass pokemon that could help, but considering Breloom and Ferrothorn aren't available in-game, there aren't many options. I was considering Cradily, but I would have to mine for the fossil, but I've already mined every available mining rocks so far (to my knowledge).
Do you guys suggest still looking for a Cradily, and if so, I could simply use blast powder from seventh street to mine the rocks again, right? And where exactly would I go to revive the fossil?
Also, what moves would you guys suggest, and what changes should I make to my team?
Any help would be appreciated.
