If You Attack... A Mutant Comes Out

This works better in multiplayer, but not as bad as a solo deck.

The purpose of this deck is to use Mutant Protectors to get the allies into play. Since they enter play defending their health will be lower from the get go (if they manage to survive); however the upside is that all of them have a Response that activates when they enter play (only Rockslide hasn't but he comes with 6hp and retaliate).

We also have Defensive Training to get Mutant Protectors back into the deck and X-Men Instruction to return the allies into the deck.

Another fun thing is that with Pinned Down we can get a week minion as hostage and defend a 0 attack to get a minion for cheap into play. And to deal with said minion we have a single copy of Under Control and a Change of Fortune to get a benefit out of it; and to get some more value we add Riposte. All this cards could be removed to slim more the deck if desired.
