It's just wording. Be able to login to the game right before the switch happens (i.e. have paid game time) and you're golden.1) If I apply these game cards (120 Days), will I be eligible to get the senche tiger? I already have 300 paid days but my subscription status says "Cancelled" and I know the second requirement for the tiger is have an "Active" sub.
Yes, you'll get 100 crowns for every 30 day period before and 1,500 crowns for every started 30 day period after.2) If I apply these game cards BEFORE Tamriel unlimited, will it add retroactive Crowns? Such as the months after March 17th will be credited like 4500 Crowns? Or do I have to wait AFTER Tamriel unlimited launches?
It doesn't matter. All that matters is that you've got time remaining on your account when the switch happens. It doesn't matter how you've paid for that.3) In sum do I need a credit card at all to keep my subscription active? Or can I just replace it all with game cards from NOW ON?

In addition, you'll be automatically enrolled in ESO Plus for the remainder of your subscription period. You'll receive the full benefits of membership, and 1500 crowns for each 30-day period remaining on your subscription. For example, if you have 30 days or less remaining, you will receive 1500 crowns. If you have between 30 and 60 days remaining, you will receive 3000 crowns. 60 to 90 days, 4500 crowns.
