mtg lost caverns of ixalan booster box MTG: The 2 Traditional Foil + 98 nonfoil cards Magic the Gathering Lost Caverns

This is good for any Elf deck, but it's especially good for Commander decks based on the mighty Rhys the Redeemed, which is all about 1/1 creature tokens

For example, if you attack with a 5/5 creature with trample and it's blocked by a 2/2 creature, you can assign 2 damage to the blocker and 3 damage to the defending player

Baymax - Giant Robot will likely be seeing a lot of play, since his Universal Shift ability makes him playable on top of basically any characters on the board

On the Ruby/Sapphire side, you get two Sumerian Talisman, which could be useful in a challenge-focused deck

Id consider this if I just wanted more mana fixing in a 3+ color typal deck, maybe in something like 5-color slivers or dragons, but most 2-cost mana rocks you plug in will be better
