Using my 75, heres a brief sideboard guide for some of the more popular decks: Blue Piles: Out: 1x Shattering Spree, 3x Damping Sphere, 1x Chrome Mox (not vs Standstill), 1x Fable of the Mirror-Breaker (Not vs Standstill) In: 2x Alpine Moon, 2x Dead // Gone (Not vs Standstill), 2x Unlicensed Hearse Additionally, if you suspect they have Tinker: Out: 1x Legion Warboss, 1x Shatterskull Smashing In: 2x Grafdiggers Cage PO Storm: Out: 4x Fable of the Mirror-Breaker, 1x Chrome Mox, 1x Simian Spirit Guide In: 3x Shattering Spree, 2x Grafdiggers Cage, 1x Pithing Needle Aggro Shops: Out: 3x Maddening Hex, 1x Pyroblast, 1x Trinisphere, 1x Thorn of Amethyst, 2x Fable of the Mirror-Breaker In: 2x Alpine Moon, 3x Fury, 3x Shattering Spree Stax Same as Aggro Shops, but instead of Fury, you bring in Grafdiggers Cage and Pithing Needle
At one point, I could have easily made this a top 20

This applies to damage dealt both to creatures and players
Like the Mega Evolutions found in this set, Mega Charizard EX has a silver border around the rule boxes and the Mega Evolution logo
