While Star Realms and Hero Realms can play with just two people, the games also support battles between bigger groups, and later expansions have introduced extra gameplay elements and even co-operative play but theyre not collectible card games, so everything you need to play can be found in the core sets
In the Pokemon TCG, for example, card rarity includes the labels common, uncommon, rare, ultra rare and even the elusive secret rare (theres also the promo category, which can contain rare holo cards only given away at special events hence the term promos )
The Umbreon VMAX alternate art secret rare aka Moonbreon from the 2021 Evolving Skies expansion is widely considered one of the best modern cards from the TCG, with the character garnering extreme attention on the secondary market
Definitely recommend saving at least 1 master set of these
What do you think of the new legends from Kaldheim s Commander decks and which do you want to build around
Growing this with noncreature spells is quite doable, and there are a few draw 2 effects in the format too that will trigger it
