With the shortage of normal layers, I knew that Horde of Notions would be almost entirely piecework. What I didn’t know was what exact pieces I would be cutting and from what copy of Horde I would take each piece. As a result, I ended up using one more copy of Horde than I needed to because I was wasteful with some early cuts.
One suggestion I've received regularly is to raise words or mana symbols. So far, this Horde of Notions is the only card I've done that with, and only with the symbols in the activated ability.
