Power creep isn't all bad; there's an assumption that the current "power level" of the game is correct, but that isn't always the case. Keeping in mind I think there have
always been balance issues in the Pokémon TCG, I actually think HP scores
need to be higher. It gives the powers-that-be more wiggle room when designing cards. There are some cards, like the generational "Draw 3 cards." Supporter, where I really have to wonder if power creep ought to have hit it sooner, upping it to "Draw 4 cards."
Now, I do
not think attacks need to hit harder, that certain Abilities need to be stronger, etc. so we're not talking across-the-board power creep.
So... yeah. This is how I prepare for power creep. I analyze it, and see that it ain't all bad so it is a little easier having to replace old favorites.
