Hi everyone ,
I was first building a sand-based team but then i went for this...what do you think about it ? What are the most weak points? I think Tyranitar choice scarf can have his good advantages, for example with a koko tytar lead i can take down landorus (jolly max speed) with DGleam + Ice Punch instead of getting wrecked by an EQ even though i know scarf landorus is still pretty common.
Thanks everyone.
