box of booster packs Pokemon™ Scarlet & Violet Series 4.5 Bundle Box, 1 ct The Paradox Pokémon—Iron Crown Pokémon TCG: Mega Evolution—Chaos Rising

Volcanic Rimfire is more of an essential piece that allows you to summon more potent cards

This card gains 300 ATK for each Guard Counter on it

Of course, you also get some pretty cool stuff along with the packs like excellent damage counters (the coolest looking so far) and a Mimikyu promo card

Pick whatever approach seems best in your mind

Note that all the new MOM precons come with a bonus 10 planechase cards (5 new and 5 reprints) that can be used if you run the planechase variant of Commander

The way Bandai is handling the game gives it a real chance to be successful long term, and I hope they stick with that
