My advice is to play a few games and notice if you often run out of cards to play
Meanwhile, Arasta generates a spider any time an opponent casts an instant or sorcery and Twin-Silk Spider gives you two bodies right away
Even the ability to take out multiple additional card types combined with the ability to take out multiple copies of that card, or multiple copies of the same token, does not come close to compensating for sorcery speed
you may look at the top card of their library any time, you may play the top card of their library, and you may spend mana as though it were mana of any color to cast spells this way.

It's advice that Brown echoes, saying that local game stores should "consider reserving some Play Boosters to use for play throughout the season if [they] anticipate running out ahead of time."
