In the Simulator events, there are lots of weird, random teams to fight against in a variety of environments.
Put a Simulator in the Story area. Every week, refresh it with new random teams.
There should be 20 or so nodes in it, with levels going from 30 (on the left) to 100 (on the right). Each time a node is played, levels should increase +5 (on the left) to +30 (on the right). All nodes are playable – they aren’t linked to previous nodes.
Prizes should be modest, just like nodes in the prologue. ISO 20 (x4), tokens, boosts, healing packs, ISO 100, ISO 250, and occasional surprises. The only prizes are on the nodes. No Alliance or Season prizes, and no points for clearing nodes.
This would provide a good area for testing out different teams at different levels against a good variety of strange teams.
