My friend and I battle a lot, and he came up with a new strategy of using a Shuckle with Protect, Rest, and Toxic. It gets really annoying and the Toxic counter eventually destroys all my Pokemon. I've countered the Toxic with steel Pokemon and a Grimer, but he just uses Protect on my moves, and when he gets low, the Shuckle rests. Can someone please help me?
1) Boosting Sweepers with an immunity to Toxic
-Swords Dance Lucario
-Calm Mind Cobalion
-Shift Gear Klinklang
And much more.
You can combine it with boosting move or not, but Substitute gives an immunity to Shuckle's main damaging move, Toxic.
Taunt will destroy this Shuckle, disallowing it to make us of any status move and leaving it vain for 2 turns.
