I started using a 4 colored deck after I made a mistake one day and thinking I had a flush when I didn't!!! Now it just looks odd not seeing 4 colored decks on sites when I play
.
I use it most places, not all. And only started maybe 6 months ago, and to my own surprise, loved it immediately. I'm a bit of a purist when it comes to many things, so at first felt like it was a 'crutch', and I was less of a decent player for using it. And I was also afraid it would
become a crutch, which it has to a small extent. I think it's at Carbon where you look at your hand history, and it flashes it back w/2 color deck, and it's extra work. lol
