• As many different CMCs of artifacts as possible (for Rebbec)
• Mass damage effects (e.g. Pestilence), which I use when my creatures have protection from that CMC
• Ways to make Rebbec an artifact (so he gives himself protection)
• Avoiding equipment (such as Sword of X and Y), as Rebbec's protection makes equipment difficult to use
