The Lorcana Gateway Box brings together mechanics from the first four chapters of Lorcana, meaning it includes cards from Into The Inklands, Floodborn and more that said, it doesnt include location cards
A New Kind of Commander It isnt often that a named mechanic only appears at rare (Hideaway in Lorwyn is one of the few such examples), but Companion makes sense
Perhaps you'll open an Enchanted rare, the rarest cards you can find in a booster
Pinging for 1 damage is negligible on its own in Commander, but certain decks in the format such as Group Pain decks led by Mogis, God of Slaughter or Kaervek the Merciless load up on these types of cards and the damage quickly adds up: when you're running Immolation Shaman, Harsh Mentor, Furnace of Rath, Manabarbs, and similar effects
In this new set, the devious and power hungry glimmer of Disney's sea witch Ursula, who was freed from the Illuminary in the second set, Rise of the Floodborn, is ready to put her plans into motion and take over Lorcana with only the players and their trusted glimmers standing in her way
