What i don't get about Link Spider and Missus Radiant

So everyone is like spam tokens summon those and your problem is solved, ok then.

But what do you do next turn after it inevitably dies? That's the part i don't get. Because you can't just summon another one because you can't play 4 link spider.

How is a non Link extra deck deck supposed to spit out links and keep them on the board as extra space is scarce when they die so easily?
