Kaldheim brought us Magda, Brazen OutlawMagda, Brazen Outlaw, which gave a power boost to other Dwarves you control, created Treasures, and let you sacrifice Treasures to search your library for an artifact or Dragon card-- instantly evocative of the Dwarven quest dramatized in The Hobbit
The Ruby/Sapphire starter deck leans heavily into the Dual-Ink mechanic that Archazias Island is really known for, letting you leverage fun and creative combos between a diverse set of cards
Valakut decks Not only does it turn off the Molten Pinnacle You get a free shot at straight up killing Primeval Titan
Lands are like the Pokmon TCGs energy cards - except instead of attaching them to a unit, you place them on the field and tap them each turn, like a resource pool
