The first one, Brave and Brazen is a well rounded deck based on an engine that rewards challenging your opponents to put pressure on their board and also trigger the abilities of other cards to gain various advantages
Some decks even base their strategy around lands, like the landfall ability, so those deck builders stuff everything they can into their deck to make sure they dont miss any triggers
If your Basim Ibn Ishaq or Tamiyo gets killed, Mox Amber provides little value
My initial impression is that he definitely doesnt seem as flashy as some of the other face commanders in these precons, but his evasion and ability to stock your graveyard and provide you with card selection definitely with the My Will Be Done ability make him very synergistic with the rest of the deck
Its a mechanic that grants both card and mana advantage, since it pulls spells from the deck and casts them for free
I recommend wooden boxes for serious collectors because they offer sturdiness and a premium feel
