Fantastic ally on Leo Anderson, given it synergises well with his main ability

Main issue Leo has, is that eventually you run out of space for allies, which basically blanks your ability outside replacing allies with other allies, but with G-Men as long as you keep a free slot for them you can keep playing them using Leo reaction and enjoy a 2/2 tanking (or possibly more with The Star) and +1 to all your stats for a turn as long as you have one resource, which will get refunded during upkeep.

Just don't let them get defeated! I don't think the forced effect will trigger from the discard pile!
