Starting with generation 6, I have reason to believe the sequence length changed to 360 (10 booster boxes)
In some ways, it sucks to play such an omnipresent threat in a casual environment, but we certainly play enough instants and sorceries to justify his inclusion if we wanted to
Sorting through these options is made easier using the rarity filters, allowing you to distinguish between standard printings and the more elusive versions of cards like Blue, Loyal Raptor or the various Compy Swarm iterations
You then get to do some fiddling about with that number of cards being on the top or bottom of your deck but that isn't the important part

So long as you have at least one creature out, its as good as a basic Forest
