If he cant leave Ixalan, hell burn the plane down
When an MTG Battle card is played, its controller chooses a player to be its protector (there are restrictions on this depending on the Battle type)
This can be an especially useful card in decks that already have an expendable board like Anhelo, The Painter or Lagomos, Hand of Hatred, or in spellslinger everything can be reused decks with commanders like Kess, Dissident mage
Primal Genesis Primary Commander: Ghired, Conclave Elite Secondary Commanders: Atla Palani, Nest Tender and Marisi, Breaker of the Coil Tertiary Commander: Tahngarth, First Mate If youd rather attack with creatures than cast spells, than Primal Genesis is the deck for you
Best is to just look at the future, and use the past as knowledge
