Every attack step my board is capable of producing roughly 150 tokens to attack and end the game. Except of course I hit the token limit so I cannot actually make most of these tokens.

At the same time opponent is gaining life for every one of these tokens that never actually appear.

This is a fundamental game breaking imbalance that you have created due to this artificial and ridiculous token limit.

If my tokens don't get created then opponent should not be gaining life from them. End of story. Yes that's obviously counter to the rules of the game but then not giving players their tokens that they're generating is also completely counter to the rules of the game.

As it is you build your deck properly and play well to get into a winning board state only for opponent to gain life into infinity whilst you are unable to attack and end the game. This is nonsense.

Regardless of what limitations the Unity engine might put upon you, there is no such limit to putting a nice big number on a stack of tokens and saying 'here you go you have 1000 insects' or whatever. This is trivial stuff. Likewise batching the triggers into a single trigger so players don't have to get carpal tunnel pressing Decline 150 times is, I would hope, trivial stuff.

It's been seven years. Why is there not a Decline All button when we are facing 150 triggers? Why is there not 'Ignore triggered ability' function for any of our permanents that would fix the entire game overnight? Literally.. all you need is a boolean that says 'the player is ignoring triggers for this permanent' attached to a little popup menu. Done. And all of a sudden the game is 100 times more playable, fun, efficient, less straining for your servers and less abusable.
