extra booster box one piece Booster: Memorial Collection [EB-01] All cards in this latest release are EXTRA BOOSTER -MEMORIAL COLLECTION- −

If a spell or ability allows you to copy a spell on the stack but doesn't specify that the spell is cast, that spell wasn't cast and won't be counted by paradox abilities

Then youve got Sage of the Beyond, which makes any spell you cast from somewhere other than your hand cost two less to cast

The most immediate thoughts I have about casting Nexus of Becoming involve doing so off of Mishras Workshop and making 3/3 Emrakuls and Portal to Phyrexias, but I would play it in basically any ramp deck in any Cube

Furthermore, we are unable to replace cards
