What is the content of Menagerie errata or where can i find it? Crlundy names it as reason for additional new=old Oracle version (which is 1E).
There's no "Menagerie errata."
The online Oracle now says +2 Cards instead of "draw 2 cards." The reason is that when Oracle is someday reprinted, I bet I will change it back to +2 Cards (it changed to get rid of a centered +2 Cards, but it could have just had an embedded +2 Cards). Stef wanted to make the change in advance and I said sure. Obv. it's only relevant for Way of the Chameleon.
Online Champion also says "first" (and has for a bit I think); that's an official ruling on Champion that isn't clarified on the printed card text yet.
