Bonus Tip: When youre building a deck for a Constructed format like Standard or Modern, as well as the 60 main deck cards, you can have an additional 15 cards in your sideboard (if you use one)
Armix, Filigree Thrasher could be a good inclusion, giving another way to put cards in your graveyard as well as removal
For newer players, what that means is that if you tap a Forest for a mana you can get another Green mana, but if you tap something like a Watery Grave for a Blue mana, you can also get one Black mana for free
Rayami, First of the Fallen, aka Soulflayer as a commander, is a card that I dont know that I fully understood the first time I read it
White has only wrath and balance if its lucky while black has damnation and a shot at removing him with sacrifice effects
