Festival of Embers bears a striking resemblance to Past in Flames, a classic card that can put in work in both combo and value lists
Whichever one you go for, make sure to pack your deck with evasive creatures so you can shift the seat of power when you need to
These tokens can have various effects and interactions
Both these cards are incredibly mana-efficient proliferate engines in our deck and any game where we can keep one of these on the battlefield is a very favorable game for us indeed
With those tokens we can create mana of every color, which excluding niche case thing like getting through a Norns Annex, Im not sure is really relevant without steal effects that dont provide the mana as any color clause
Narset starts at five loyalty and her activated ability costs two loyalty, so even after her controller has refilled their hand with their best two spells from the top eight cards of their deck, she remains on the battlefield at one loyalty to continue denying extra cards to the opponent
