Some one suggested a Sentinel.  Nice.  That allows for a purple golem.  Just need more Golems.

If I do get more golems, whether in trade or when they add them to the store future ones could include:

• Silver w/ Red (Colossus)
• Medium Gray with Blue (Thanos)
• Purple w/ Blue (Sentinel/Galactus)
• Red w/ Gold (Ironman)
• Bright Blue w/ Red (Captain America)
• Dark Blue w/ Yellow (Beast)
• Gunmetal Gray w/ Green (Doom)

Heh.  That’s a lot of golems.
