I dont think so, SM is too stupid to do that. From what I see, power level is only too restrict super new powerful cards, If old cards were that strong, than yes, than MAYBE something will happen. But remember, the Coredom ability has a 4 power level, you and your opponent would have to be tied 2 V 2 for that to work, which is also why its ability is so grandiloquent and strong, so overall, I think everything will stay the same.Also, for the battle gears, I think its cool that you dont have to match the attribute on the reference card, but also having the option for your gears type (bronze, silver and gold) match the gate color, that should sprout many fun new strategies!
