First, if someone says they're going to have Lutri be their companion, it's the easiest thing to fix: you just say, "Hey, did you know you can't do that?" and it likely changes what their deck is doing very little
The only personal stance Im going to be taking in this piece is that theres an entire side to this discussion that were just not having right now
I do think they want to slide back and forth through different expressions and play the one that suits their needs at that given time. Of course the Historic format was already unique to Arena as well, if technically playable with paper cards
Random packaging: Original Pokemon cards in jumbo format, no Pokemon cards in standard format (it is not recommended to buy 2 Jumbo packs, as Pokemon cards can be distributed across 2 different packages)
Giving Squirrel creatures menace and +1/+1 counters fits well in decks helmed by Chatterfang, Squirrel General, Hazel of the Rootbloom, and The Odd Acorn Gang
So you play it, gain a very tiny amount of game information, sacrifice it, and replace it in your hand at the start of your next draw step
