However, this is not a landfall deck where mana is nearly limitless
Its four-mana ability lets you avoid the Commander tax, and it works well with cards like Emiel the Blessed and Gaeas Cradle for infinite mana combos
The cost reduction will help you put a Character in range for removal plays like Hound Blaze , making it easier to control the board without requiring more cost reduction cards to assist you

We could also consider playing green for something like Traverse the Ulvenwald
