[2019] 3 Blocking Kitesails - How Do You Determine Which Order?

There’s not really a way to tell in that situation currently. In our next update there are some improvements here, where the order is preserved when you “View Battlefield” from the order blockers screen. So you can note that the cards are under blockers 2&3, slide one of them over in order blockers, hit view battlefield to check, and you’ll see that blocker left-most in the order.

There are similar issues with a number of other cards (which one has the enchantment? Which one has the equipment? Which one is protected by Dauntless Bodyguard? etc.) The added text solution only covers some of the cases, so that's why we went the way we did

We do have an indicator for this now, but it's obviously not clear enough (since we keep getting this feedback). If you hover over the cards in your graveyard, one of them will have a hanger (the text boxes on the side of the card in mouse-over) that says "Targeted by Eldest Reborn" (or whatever), so you can tell which is which. It's on our list to make this louder/more clear, but at least it is there now.
