Another effect that works well with the extra land drop cards above is cards that allow you to play lands from zones other than your hand

There are some nice synergies that the Knight type can grant you, The Circle of Loyalty etc., so this could see Commander play for that reason

(2/5/2021) If an effect causes a creature with changeling to lose all abilities, it will remain all creature types, even though it will no longer have changeling

The only real difference is that Suplex is a sorcery, but for that downgrade, you're exiling the creature or artifact instead of just destroying them

Being a red card means you can clear his way with red removals (Lightning Bolt/Unholy Heat)
