Once players get more comfortable with the game, they can start to build their own deck with cards from both sets, keeping in mind that there are some rules for custom decks
Green ramp decks now have Karn, Ugin, Sky Sovereign, Garruks and Nissas as well as card quality non-creatures at the low end
To extend the effect of your song, this deck also includes Max Goof, Rebellious Teen that allows to get back a song from the discard by paying one Ink and Powerline, Worlds Greatest Rock Star that can play a song for free from the top four cards of the Players deck every after playing any other song
Much like Ghalta, Stampede Tyrant, Gishath allows you to put any number of Dinosaur creature cards onto the battlefield, but, improving on the formers ability, you can dig through the top X cards of your library to get them (based on the amount of combat damage it dealt)
Threatens are the main reason to do this
Were still fairly fresh off the back of Duskmourn and its Commander precons, so I havent had the (dis?)pleasure of facing off against The Master of Keys
