Next season's rotation has been announced, so I made a list of all competitive cards we will be losing this year. About 30 important cards are rotating, the only decks that will be completely obliterated by this rotation are Greninja BREAK and Volcanion-EX. Garbodor and Zoroark variants will take a hit from rotation, but won't be ruined. Buzzwole is the biggest loser with Regirock EX, and Strong Energy rotating, but will still be competitive. Octillery (BKT 36) Zoroark (BKT 91) Brigrtte (BKT 134) Float Stone (BKT 137) Parallel City (BKT 145) Super Rod (BKT 149) Frogadier (BKP 39) Greninja (BKP 40) Greninja BREAK (BKP 41) Espeon EX (BKP 52) Garbodor (BKP 57) Bursting Balloon (BKP 97) Fighting Fury Belt (BKP 99) Max Elixir (BKP 103) Puzzle of Time (BKP 109) Skyla (BKP 122) Team Flare Grunt (GEN 73) Regirock EX (FAC 43) Carbink (FAC 50) Carbink BREAK (FAC 51) Zygarde EX (FAC 54) Strong Energy (FAC 104) N (FAC 105) Volcanion (STS 25) Volcanion EX (STS 26) Special Charge (STS 105) Professor Sycamore (STS 114) Mewtwo (EVO 51) Mew EX (XY126) Loses per Set: BREAKpoint (9) BREAKthrough (7) Fates Collide (6) Steam Siege (4) Generations (1)/Evolutions (1)/XY Promos (1) Worst Loses for Standard Professor Sycamore N Float Stone Brigette Super Ror Garbodor Max Elixir Puzzle of Time Parallel City Special Charge Overall, not that bad of a rotation. We lost a lot of important trainer cards which should slow the meta down, but no prominent archetype's were ruined, and the meta won't really change as much as it usually does with a rotation.
