I am really looking forward to this set. Here are the posts for it that I am using to prepare for when I get my hands on these cards.
Ikoria Companion Cards
Ikoria Mutate Cards
Although not really aimed at Ikoria, I am including here selections for Guild Devotion
And then, there are the five wedge commanders, the cornerstones of this set.
Ikoria Abzan Nethroi for Commander
Ikoria Mardu Snapdax for Commander
Ikoria Jeskai Vadrok for Commander
Ikoria Sultai Brokkos for Commander
Ikoria Temur Illuna for Commander
