While an English booster box yields more cards overall, it doesnt guarantee specific rare pulls
I think the default will be fetch a basic Plains and make a 2/2 when the battleifeld isn't pushing in any directions, and that's pretty good for three mana
However, if you cast See the Truth from anywhere other than your hand - lets say the graveyard thanks to something like Snapcaster Mage - then you get to draw three cards
So, when it dies, you'll improve your hand and ramp, and both of these effects are great when you're behind
Shiny Galarian Perrserker has already gotten two major cards, including a Gold Secret Rare in Sword & Shield Rebel Clash and a "Baby" Shiny Pokmon card in the special Shining Fates set
So far, it seems like the six-card draws are the only way to organically obtain a baby Pokmon (not counting Togepi, which can appear in any set)
