MYTHIC sheet: contains one Foil Discard Filler with No Hologram
Niv-Mizzet, ParunNiv-Mizzet, Parun is a powerful commander in his own right, but this deck is built to lean on Firkraag for card draw and there are only 10 cards among instants and sorceries
It has above-average mana/ramp, which makes sense given its high average cmc
This is very much a final win condition, potentially leading to some huge blowout as it can buff your entire board +5/+5 at instant speed
This same concept is applied to the list cards or other "bonus sheet" style mini-sets
If a spell, ability, or effect states that a player can do something only any time they could cast a sorcery or only as a sorcery, it means only that the player must have priority, it must be during the main phase of their turn, and the stack must be empty
