Shadowverse

I don't think I've ever collected more than 20k, but I don't think that's too much because I barely stack gold – by the time the Dungeon/Necropolis comes around, I've saved up a couple of thousand, and that's a record (I was playing a lot back then).

But playing for a year and a half with a Roach and a Sprite in unlimited mode.

And I have fun playing with a Rushing Bishop in unlimited mode. I threw one random creature into an old deck, and it's fine.
