In order to include so many characters, they even printed 41 legendary creatures at Uncommon
Out of the creatures, I like Thermo-Alchemist as an effective third iteration of the two main cards from the deck, Night Market Lookout and Spireside Infiltrator
Fetch lands are incredibly good because they fix your mana , can get basic or dual lands , generate two landfall triggers , and provide a shuffle effect
Generally, your deck will want four to six board wipes on average
On the other hand, the current Mystery Booster pack EV is quite a lot higher than the actual cost of a given Mystery Booster pack
I really love about this new cycle of if you control your commander free spells since they encourage you to go ahead and be proactive by casting your commander cards rather than holding back mana to cast reactive spells
