1. It depends. 3 is usually a good number. A Chocolatier, another RE, or turnskip could fill in the 4th. An AoE buffer, e.g. Huang Long or Vesta, is typical of the last slot, though a self-buffer will always suffice. I'm personally using 3x RE, Chocolatier, and a Lilim for maximum jankiness.

To answer your question, it varies, but I prefer 3. 2 is suboptimal unless you happen to have 2 skill nullifiers.

2. It's typically better to HUR something, but a Redeye deck typically needs more than one copy; 3 is the best in my opinion. At the rate you're going, it would be better to keep the two separate.
