One setting of EDH that is my personal favorite is 2-Headed Giant or 2 on 2 with planechase cards if you wanted to make the game even more random and whimsical
Occasionally you will be fearful of artifacts and play as many spells that deal with them that also offer redundancy to the deck as you can
This is a gross simplification, but if someone cant tell that a card is misprinted at a glance, theres not much appeal to it
What are your thoughts on classes
Ohran Frostfang, Toski, Bearer of Secrets, Bident of Thassa, Coastal Piracy, The Indomitable, and Reconnaissance Mission immediately come to mind in those colors
While classic tribes such as Elves and Goblins are home to a litany of deck-building options, other, more fringe tribes also offer players a variety of choices when picking a commander
