About the pure coincidence thing of score and electrum, without spins these are one and the same unless I'm mistaken
(which I doubt )You gain as much score as you do electrum if you don't spin.
Edit: with EM you seem to score 35 and gain 40 electrum on AI3, so that's not the same.
Love to try this for faster score, EM makes a big difference and Shrieker Rush (my most used rush deck) doesn't EM unless your opponent is in terrible luck
