Arachnus Spinner turns every Spider you control into a repeatable Arachnus Web staple gun, locking down the biggest threat on the board at instant speed every turn cycle. The six-mana body is slow, but in Shelob, Child of Ungoliant decks the Spinner is a payoff card, not a ramp target.

Shelob, Child of Ungoliant
Shelob, Child of Ungoliant generates a Spider army that makes Arachnus Spinner's tap ability fire every single turn, while Shelob's deathtouch clause means the Spiders doing the tapping are already threatening enough to survive trades.

Arachnus Spinner is a Commander card through and through — the payoff scales directly with the number of Spiders in play, and tribal synergy that narrow only reaches critical mass in a 100-card singleton format with a dedicated commander. In Legacy and Vintage it's legal but invisible; no competitive shell wants a six-mana do-nothing-the-turn-it-enters creature when removal is free and fast. Pioneer and Standard don't have it, which is irrelevant. Commander is the only place Arachnus Spinner earns its roster spot.
