My "favorite" one of those has to be changing the word upgrade to card with regards to tokens triggering effects. Captain Spock on the Enterprise-A with Valtane would have been nice.
It still is nice. There are two WORF rulings that explicitly allow such an interaction.
I know a lot of people will tell you that the Tournament rules (to which you were referring) are dated after those rulings, but the text in question was in place in an earlier version that pre-dated the forum rulings. So the most recent word from them on the subject (and again, quite explicit) says that you can trigger the Enterprise-A's text and Valtane's with the same Scan Token.
