Not necessarily Pokemon changes but more so ability/move changes. Freeze Burn and Freeze Shock should be 1 turn moves. It's only exclusive to Black and White Kyurem so why make it 2 turns.
And I feel that Turboblaze and Teravolt should boost Fire-type and Electric-type moves to let them be a bit more than Legendary versions of Mold Breaker.
yes but make them then let it not move for one turn after that or reduce its own stats after using it and always activate its secondary effects with 100% chance too???
