For as much as this set feels like a love letter to fans made by fans, there is one specific aspect that really rubs me the wrong way and adds a slight blemish to it
If the target creature card is an illegal target as Golbez, Crystal Collector's last ability tries to resolve, it won't resolve and none of its effects will happen
Early versions of the deck involved a "choose a job" system and other decision trees before each game of Commander
(Choose any number of permanents and/or players, then give each another counter of each kind already there.) Pay 1 life, Sacrifice another creature: Put a -1/-1 counter on up to one target creature and draw a card
I have low expectations for the Staff as a card, but as a depiction of Yuna its got a lot to like
Overall, Shimmering Skies Emerald/Steel Starter Deck is great for early games and learning to play, if you are looking to get more serious about Lorcana though, something higher on this list might be better
