You can see my take on a five-color mana base
that it is the best because it fosters an environment where Teferi and Narset (and sometimes Dream Trawler) are all predictably on the battlefield, often all at the same time
It offers a higher chance of pulling multiple rares and has double the odds (25% vs 12.5%) of containing a valuable card from "The List." However, for any new set, this question is irrelevant as only Play Boosters are available, and they were designed to provide a very similar, high-value opening experience
In deck building, this balance is called the "mana curve." Each spell has a mana value, which is the total mana cost of a spell
This one lets you cast Dollmakers Shop early to start churning out tokens and then unlock Porcelain Gallery later on to pump up your entire team and swing for big damage
The question is whether there is room for it alongside competing options like Corpse Appraiser and Fable of the Mirror-Breaker
