mtg captain america commander deck Secret Lair: Secret Lair x Marvel's (Non-Foil Edition) : Toys & Games 10 double MSC] Captain America, Team Leader

Each player needs a Disney Lorcana deck of at least 60 cards to play

Protecting it is non-negotiable

The card penalizing even your own nonartifact creatures that join battle afterwards represents that aspect very well

While a TDFC is on the stack and while it's on the battlefield with its front face up, it has only the characteristics of that face

If there are additional costs to cast a spell, or if the cost to cast a spell is increased by an effect (such as the one created by Thalia, Guardian of Thraben's ability), apply those increases before applying cost reductions

I would never add these to a casual Commander deck
