Arena Noobie Question I just started playing Arena for the first time the other day. I wasn't happy about it's announcement when I have had played MTGO for so long and had amassed a large collection that I had assumed I'd have to repurchase and earn again on a whole other platform. Turns out Arena I can play for free and is only standard and limited so that is neat. I'm currently just playing bots to build up my collection so I can actually make decks to player later. How can I play for other set cards? So far I've only seen where I can play mastery stuff for the 2020 core set. Is there mastery stuff for war of the spark so I can earn cards for that set too?

Thanks in advance. I'm new to this and just messing around.
