­Ant Queen pretty much blows this out of the water, doesn't it?

Mostly; reach matters, but probably it doesn't matter quite that much.

Well, okay, right now this is like super stally since on your next turn you can assumedly drop six of those in combat. Then you can keep doubling that number each turn. Halving the activation cost means you get twice as much bang from it each turn. Maybe the tokens should be temporarily? Also, why can the webs attack?

> : Create five 0/2 green Web creature tokens with reach blocking attacking creatures as you choose. Sacrifice them at the end of combat. Activate this ability only during the declare blockers step.

I'd go back to 0/1 webs and give the spider some bonus like "~ gets +1/+0 for each Web you control"

Took away the token maker, ability targets Forests, making this closer to what I imagined, which is a spider that literally blocks off whole sections of the forest with webs between trees. Didn't make sense to have it work as well on things like Plains or Islands.
