Sokka and a boomerang
We're going to speedrun through dungeons and get haste and pump with Kick in the Door, draw tons of cards and make our creatures lethal with Fists of Flame, untap all our creatures give them haste and cast our hand with Traitorous Greed, give trample and draw tons with Ancestral Anger
Going by TCGPlayer, the special issue serialized Praetors continue to sell in quantities akin to other popular, but significantly cheaper, serialized cards from the same set
And a powerful new event, Divine Departure (Kamusari) , gives red decks a flexible answer by KOing an opponents character or serving as a defense counter (this card is so good its among the top chase cards)
If an Adventure spell leaves the stack in any way other than resolving (most likely by being countered or by failing to resolve because its targets have all become illegal) , that card won't be exiled and the spell's controller won't be able to cast it as a permanent later
The first player will skip drawing a card on their first turn (a common TCG rule to balance advantage)
