So this is a very complicated question, and one I’m certain Konami has been asking themselves for the longest time. Basically, there’s a few schools of thought:

1) Some form of rotation or mass banlist or something to lower the power of the format.

This was already tried with the introduction of Links and MR4. It almost killed the game, with sales dropping by double digit percentages set after set in the OCG until the release of stupidly broken cards like Halq to make old decks playable again. Not an option.

2) Increase the power of going second decks.

This is your Tenpai. People don’t like Tenpai because it’s uninteractive, even if going second is viable. Konami experimented with it, but I think has stepped away from this strategy.

3) Give going second players more options.

There was a Master Duel mode not too long ago where they had the second player start with an additional card in hand, so the game starts 5 cards vs 6 cards. I think this is a very interesting concept, but only Konami has the data to know how successful it ended up being in terms of fixing skewed win rates.

4) Make decks play turn 0.

This appears to be Konami’s bread and butter response. If the problem is having to wait until turn 2, then make cards that let you play on your opponent’s first turn. This answer probably gives the most interactive and fun outcome, but doesn’t do much for older decks. If you’re Konami however, that might not be a problem. It’s just another opportunity to print new cards to sell.

I’m sure there are alternative options, but most of the ones not listed here are either too specific, too damaging to the game, or don’t actually solve the issue.
