Notably, cards with replicate kind of act like storm spells in the sense that you create copies of them based on the number of times you pay their cost, as is the case with Lose Focus or Gigadrowse
In the example below, the Endbringer, the top layer of the card has split, showing us the piece of wood embedded within the card
This applies retroactively, too, to the many MDFC cards printed before now
The core idea of the deck and the Commander are supported relatively well
Effects like Duress specifically interact with cards in your hand, and thats the only zone the game recognizes for discarding
Combined with Flying, you now have a perfect combination of keywords, as they allow a creature to attack evasively and defend against other attackers in the air or on the ground
