M-lop and Kyurem are the definition of a core in Nat Dex.
The concept is simple mega lop crushes offense due to its high speed base of 135, fakeout, a solid stab combination of return and cc and U-turn. But it struggles to break through walls. But it can bring in kyurem with U-turn.
Kyurem with its decent speed base of 95 deadly coverage of freeze-dry and earthpower, okay bulk/atk and its pressure ability is a nightmare for every defensive mon.
It also justifies not using an ice move on lop.
But its often revenge killed by faster, super effective Attacks.
